Can
we have boilers manufactured under our private label?
Yes, three options are available
MFG-
BY REIMERS, Underwriters' Laboratories (U.L.) allows us
to "label" the boiler with your name if we include: "Mfg.
by Reimers Electra Steam Inc., Clear Brook, VA. on the
bottom of the label. There is no charge for this service.
Our standard computer generated label can be used or you
can provide your own.
MULTIPLE LISTING, Our name can be eliminated completely from the exterior
of the boiler if a U.L. multiple listing is obtained by your company.
U.L. has an initial charge for this service and an annual fee Reimers
has no extra charge attached.
SPECIFIC DESIGN: Due to our CAD/CAM capabilities and our in-house CNC
machines, it is feasible to design & produce equipment to your specific
requirements. Internally it will be a "Reimers" boiler, but externally
it will resemble your equipment in color/shape/form. This option is always
more expensive because of limited quantities.

What
suggested spare parts are required on site?
We do
not suggest that all or any replacement parts will be required
for one to two years service. With proper maintenance,
replacement parts are seldom required within this period.
In some cases, specific items (i.e. elements) may need
more frequent replacement. This is a factor of water treatment,
maintenance, etc. The type and quantity of spare parts
kept on site will vary with the application. Some high
priority (surgical rooms & primary process boilers) will
necessitate a replacement stock of heating elements, gaskets,
fuses, and selected controls. However, Reimers does maintain
a consistent stock level of parts ready for immediate shipment.
Contact our factory Monday through Friday prior to 2:00
PM EST we will rush your part out the same day.

Are
stainless steel boilers available?
Reimers
manufactures stainless steel electric steam boilers for
those applications requiring pure steam and using de-ionized
water having a minimum specific resistivity of 1 megohm/cm.
These units provide a stainless steel surface to all wet
areas and are designed and constructed within the scope
of A.S.M.E. Code. This limits the design pressure to 100
psig and maximum pressure vessel size to 5 cubic feet.
We offer various models from .15 to 12 B.H.P.

Is
steam cleaning still practical as compared to pressure
washers?
Steam
cleaning produces considerably less water and chemical
runoff than pressure washers. It also allows the operator
to "dry" the part with saturated steam after
cleaning. This speeds up the process and improves productivity.
For heavy steam cleaning in a production environment, we
recommend our model RBH30Z-20651 with syphon steam gun.
This combination provides the versatility of using steam
and/or detergent in mixture. If it is feasible, we suggest
a stationary unit with appropriate steam lines to various
locations with steam cleaning outlets. This eliminates
moving a heavy unit (500 lbs. or more), trailing water
hose and heavy electrical cable. This unit is a dry-type
steam cleaner, which ejects raw steam at 80 to 90 psig.
The only wetness you will get is the detergent which is
syphoned into the end of the steam gun and mixes with the
steam in the gun. The amount of detergent is controlled
by the operator with an adjustable syphon valve on the
steam gun.

What
should the feed water quality be?
Calcium
is the biggest nemesis. Water of less than 15 grains hardness
is preferred. For carbon steel boilers, do not use de-ionized
water. Specific resistivity should be less than 100,000
ohms/cm. For stainless steel boilers, you must use de-ionized
water of at least I megohm/cm specific resistivity.
^^Back
to Top^^
Can
distilled water be used with these boilers?
If distilled
water must be used, it will be necessary to add a "pinch" of
salt once each week to the water. This will permit electricity
to pass through the water for the probe controls. We suggest
that "soft" treated water be used in lieu of distilled
water and that the boilers be given a daily blowdown. This
will prove less expensive and will work well even in hard
water areas.
^^Back
to Top^^
Please
explain blowdown tank installation & operation.
Purpose:
The blowdown tank is designed to prevent high pressure
steam and water from entering into drains and possibly scalding
someone. Therefore, it is provided with a chamber that will
allow the blowdown water to cool before discharging and allow
the steam flashed from the blowdown water to vent to atmosphere.
Design:
Our blow down tank accomplishes this by:
• Cooling: The bottom half of the tank is full of cool room temperature
water at all times. When the boiler blowdown valve is opened, the hot water from
the boiler displaces (moves) this cool water out the overflow to drains. The
hot water will then cool to room temperature after sitting for several hours
• Pressure: A large vent to atmosphere is provided on the top of the blowdown
tank to allow the steam flashed from the blowdown water to vent to atmosphere.
It is important that this vent be piped so that the steam will not discharge
on any person.
Installation:
• Mounting: Mount on the skid provided so that the
blowdown tank is portable.
• Drain: Pipe this to floor drains (or to a bucket).
• Fill: Put water into the tank up to the drain fitting (approximately 4
gallons/ 15 liters).
• Vent: Thread the 4 ft (1.2 meter) pipe up from this fitting.
• Blowdown inlet: Connect the flexible stainless steel braided hose from
the boiler blowdown to this.
Operation:
Ensure that the tank has "cool" (120 degree F/49C maximum) water
in the bottom half (up to drain fitting). Connect the flexible stainless
steel braided hose from the boiler blowdown to the blowdown inlet. Place
a bucket under the drain outlet. Open the boiler blowdown valve for ten
(10) seconds. This completes the blowdown.
Caution:
The most dangerous part of any steam boiler is discharge of the water
either through a broken fitting, gauge glass, or blowdown valve.
When the blowdown valve is opened, it will shoot hot, scalding water
for at least 20 feet (6 meters) unless it is properly piped to a
blowdown tank. Be careful and ensure the maintenance people fully
understand the danger and operation.

What
maintenance is required for electric boilers?
Our
boilers require very little maintenance if blowndown weekly.
We do suggest that the boiler be examined after the first
90 days for small leaks (around gauge glass, valves, etc.),
internally for calcium buildup (to evaluate if more or
less blowdowns are required), clean probes, and generally
look for problems. It is a good habit to have a technician
replace the gauge glass every year, check for leaks, internally
examine boiler, clean probes, etc.

Flexible
manufacturing cells require what type boilers?
We have
observed a large demand for modular installations (flexible
manufacturing and quick response) such as those displayed
at TC2 in Raleigh, NC. These installations demand considerable
equipment flexibility with respect to physical size and
location. Our model AR8-tank unit has proven ideal for
this modular concept due to its small size (ships via UPS),
portability (provided with flexible electrical cord and
plug), power (supports up to four electric steam irons),
and state regulatory acceptance (U.L.-listed, ASME design,
Nat'l board inspection).

Where
is pressing technology headed?
We anticipate
a strong movement towards lower retail inventories with
a broader selection of garments for the consumer. This
will further emphasize the need for small, flexible contract
operations.
^^Back
to Top^^
Are
technical challenges involved with pressing equipment?
Purchasers
of new pressing equipment will be challenged with the need
to accept electronic components in the equipment. Consideration
must be given to cleanliness ambient temperature conditions.
These improved conditions will also be demanded by the
better pressing operators as the workplace advances.
^^Back
to Top^^
Is
Reimers supporting flexible manufacturing & quick response?
These
concepts have encouraged our research and development staff
to concentrate on small, flexible electric steam boilers
The result has been our model AR8-tank. We have continued
in this fashion by broadening the initial concept to include
• A
portable boiler supporting three all steam irons.
• Changing the design of our full range of small boilers (JR thru AR8) so
that they ship via United Parcel Service.
• Evaluating the development of three phase units in this physical size.
• Listing all of the above with U.L the Canadian Standards Association.

Piping
What
is a closed return system?
A closed
return steam system provides far the direct return of condensation
from the piping and process back to the boiler pressure
vessel. It is a thermodynamic cycle that utilizes the gravity
return of the condensation (water).
The
advantages of such a system are:
• No steam trap nor condensate tank
• More energy efficient
• Cleaner water
• Simpler operation
• Less space required.
A closed
return system consists of a steam boiler, vacuum breaker
(to avoid overnight flooding), steam piping to the steam
application, condensate piping (no trap) from the application,
and check valve. Same applications are: single utility
press; single steam jacketed kettle; short piping run far
irons, humidity, etc.
^^Back
to Top^^
What
is a vacuum problem in a small steam system?
This
normally shows up with the flooding of the boiler overnight.
It is not uncommon for this to happen. Vacuum (negative
pressure) is caused when the boiler is shut down with steam
pressure in it. As the steam cools overnight and condenses
(changes to water), the space left by the steam becomes
a vacuum. (One pound of steam takes up about 350 times
as much space as one pound of water.) This vacuum in the
boiler "sucks" water from the condensate tank and causes
the boiler to flood. Unless the boiler is hooked to equipment
(such as a utility press), this is more of an inconvenience
than a problem. It can be resolved by closing the ball
valve between the tank and boiler each night (open same
each morning), or by placing a vacuum relief valve in the
steam piping.

Codes
Are
electric boilers available from Reimers for use in
Canada?
Yes.
All of our boilers are built to the ASME boiler code, including
CSD-1. Each is inspected by a commissioned national board
inspector. A CSA. listing and a Canadian registration number
is provided for Canadian boilers. These approvals ensure
ease of installation and ready acceptance by jurisdictional
and insurance inspectors. In fact, one of our engineers
holds an Ontario Professional Engineer's license.

New
York City requires MEA approvals Does Reimers meet
these?
The
majority of Reimers boilers are already registered in the
city of New York, Department of Buildings. Reference the
following NEA acceptance:
MEA 84-93-E: Models R, RH 8 - l 20 & RHP l 00 -500
MEA l 76-80-E: Models JR

Is ASME code design & National board
inspection important?
Yes!
It ensures that the boiler is built to the proper specifications
to be safe to operate. In most states, it is required by
law.

Economics
What
will it cost to operate an electric boiler?
Electric
consumption:
(KW rating) x (#hours of operation) x (KW/HR charge) = cost per month.
Normally, the customer will utilize 60X or less of this amount.
Electric
demand:
In the U.S.A., the electric utility company charges companies a "demand
charge" each month equivalent to the peak amount of electricity used
during a 30 minute period during the month:
(KW rating) x (demand charge) = demand cost per month
Water
feed costs:
With weekly blowdowns, it is not necessary to use special water in these
boilers because of their larger pressure vessel and specially designed
heating elements. We do suggest "softened" water if the normal water
is very hard. This allows the blowdown to work better and reduces hard
calcium buildup within the pressure vessel. Distilled water should not
be used because of its expense. To calculate water usage:
(B.H.P.)
x (4.2 gallons per hour) x ( hours of operation) = water
used
(B.H.P.) X (l5.9 liters per hour) X ( hours of operation) = water used
This
formula calculates the maximum amount of water that the
boiler can use. Normally, no more than 60X of this volume
is used.

What
are the steam piping considerations?
It is
imperative that your steam piping be safely and properly
installed. Poor piping will result in wet steam and poor
efficiency Same tips:
• Pitch
steam and condensate pipes away from boiler a minimum of
2"/10 ft.
• Insulate piping with minimum of 2" high temp. insulation
• Size far lass of I BHP per 50 ft. pipe length.
• Maximum closed system = 25 ft. length.
^^Back
to Top^^
Is
an electric boiler economical to operate compared to
gas?
The
cost of gas is generally much less expensive than electricity.
However maintenance and installation costs for a gas boiler
will offset the energy costs. This is because electric
boilers can normally be located in the immediate vicinity
where steam is required, saving considerable line loss.
Also electric boilers do not use a flue/exhaust.
^^Back
to Top^^
What
considerations should be evaluated in buying pressing
equipment?
Quality
of design and manufacture are the key concerns of the experienced
apparel producer. After years of buying "a price," the
experienced manager realizes that the initial cost of the
equipment, especially with respect to hand irons and small
steam boilers is the smallest part of the total cost picture.
Only unseasoned contractors purchase on price alone.

Manufacturing
Will
boilers be constructed of carbon steel rust?
Almost
all steam boilers are constructed of carbon steel, which
rusts if exposed to oxygen and moisture The following steps
will minimize this problem. (Please observe "shock & burn
warnings."):
Blowdown
piping:
The boiler's blowdown valve must be safely piped in accordance with state
and local codes. Ensure that safe discharge is provided for 100 PSIG
and 338 degrees F.
Blowdown
procedure:
Turn the boiler off and allow the pressure to drop to 5 psig. Open the
blowdown valve for ten seconds, then close. Refill the boiler to the
normal operating level.
Blowdown
frequency:
The blowdown procedure given above should be followed at the end of each
working day.
Water
fill:
Never leave the boiler empty. Water and oxygen
forms rust. An "empty" boiler always has a little water
left in the bottom and will rust quickly due to the exposure
to oxygen.
Water
level:
Handfilled boilers must never be filled over the high water mark. Rust
floats on the surface of the water and is discharged with the steam if
the boiler is overfilled.

Sizing
Are
compact electric steam boilers available?
The
prime advantage of electric boilers is compact design.
Reimers provides a variety of models from table top 120v/.15
B.H.P. units to 480v/50 B.H.P. Our model RH-30Z is a good
example. It is designed for installation directly under
a utility press or autoclave. This unit is compact enough
to fit in a 18" x 18" x 30" space, yet has a large 284
cubic inch pressure vessel to ensure dry steam discharge
and long element life.
^^Back
to Top^^
How
do I calculate the power requirement for an electric
boiler?
The
basic formula used for electric boilers are as given below:
10 KW
= 1 BHP (boiler horsepower)
1
KW = 3412 BTU/HR
1 KW = 3.48 LB/HR steam (from & at 212 deg. F.)
Amp draw (1 PH) = watts / volts
Amp draw (3 PH) = watts / (volts X 1.732)
(N.E.C. requires service for 125% of amp draw.)
1 cubic foot = 7.461 gallons water
1 gallon water = 8.331 lb.
Maximum water usage = .07 GPM of water per 1 BHP
^^Back
to Top^^
How
much water do these boilers hold? Is this important?
The
volume/capacity of an electric boiler provides an indicator
of quality. Within reason, the larger the pressure vessel
(boiler), the better the quality of steam discharge and
the longer element life. This is because of the energy
stored in the additional water and steam which allows the
boiler to maintain a more constant pressure under load.
Also, calcium and sediment will be less of a problem.
