Hot
Water Heating Boiler
Model HL 36Z thru HL 180Z
|
Electric
Hydronic Boilers
Designed
for Commercial and Industrial Circulating Systems (i.e.
Swimming Pools, Water Source Heat Pumps, Comfort Heating,
Tank Heating, etc.)
Models
24 thru 54
Equipment includes a 24 volt circuit for remote sensor
operation and timers to limit initial amperage drawn
by the boiler.
Models
60 thru 100
Same as small models 24 thru 54 but to include a Proportional
Sequencer for energy conservation.
Models
120 thru 500
Same as Models 60 thru 100. Low water Cut-Off Controls
are used in lieu of Flow Switch and Proportional Sequencer
equipped for positive on-off action. Equipped for 120
volt remote control.
All
models are equipped with 120 volt Control Circuit, Adjustable
Temperature Controls, Hi-Limit Safe Temperature Control,
and Low Water Cut Off w/ Manual Reset. |

Water Heating Boiler
Model HMH 25E1B
|
Insulated Jacket, Element &
Circulator Pilot Lights, Aquastat Temperature Control,
Aquastat Hi Limit Control*, Integrally Mounted Manual
Element Control and Air Purging Switch, 24 Volt Transformer,
24 Volt Room Thermostat, 1 1/4 Bell & Gossett Circulator
No. 125, Extol Expansion Tank (with Water Fill Valve,
Air Scoop and Automatic air Vent), Pressure-Temperature
Gauge, A.S.M.E. Safety Relief Valve, and Boiler Drain
Valve with Hose Connection.
*All models are equipped with 2 temperature controls.
One manual Reset High Limit Control shuts the boiler off
if the adjustable temperature control fails. The water
temperature control is adjustable from 100° F to 240°
F. When the boiler water temperature reaches the limit,
all heating elements are de-energized. The circulator
pump will continue to run as long as there is a call for
heat from the room thermostat.
Circulator
All models contain a circulator fuse and relay. The
circulator is protected and there is no need for either
a separate fuse box or external wiring. For Models HMR
there is a circulator switch. During the initial start-up,
air is automatically purged from the system. Thus, manual
operation of the circulator is permitted if desired.
General
Boiler shells are constructed of low carbon steel to
comply under the "H" symbol of the A.S.M.E. Code and
are individually inspected. These shells are made from
A.S.M.E grade boiler plate and wrapped with fiberglass
insulation.
Heavy gauge boiler jackets are
furnished in eye appealing Blue enamel.
Elements are low watt density
which insures longer life. The elements are Copper sheathed
and pressure sealed to the flange. Models HMR are single
phase. Provisions have been made in the boiler jacket
for quick and easy removal of the elements.
All element ratings are based
on 240 volt power input. Other voltages available.
Control panels for all models
are mounted in a control box outside of the unit. This
insures easy access to all controls and more important
does not allow overheating of wires, controls or fuses.
For these reasons the circulator pump is mounted outside
the jacket. This insures uninterrupted service and long
life. |
