CH-K Series: 30, 40, 50, 60, 80, 100 RT Cooling with Standard Heating Capacities
"G" Series control package utilizing VFD solution pumps are used on the 30 to 80 ton chiller-heaters.
Each modular chiller-heater serves a dual purpose: Cooling and Heating.
Cooling or heating operation can be selected from a remote or built-in switch with a 30-minute changeover.
A two pipe hydronic system can be used to circulate chilled or hot water to a central air handling unit or to multiple
Can be vented with inexpensive Double Wall Type B Vent using Category I rules.
Vacuum vessel is hermetically sealed at the factory for a level of vacuum integrity that is unmatched in the industry,
with no field welding necessary.
Safe, odorless, non-toxic lithium bromide and water are the working fluids and operate under a vacuum at all times.
Proprietary solution and inhibitor blends ELIMINATE the need for regular chemical analysis, resulting in much
simpler regular maintenance when compared with other manufacturers.
Only two moving parts – the solution pump and the burner blower – are needed. We don't use multiple pumps as
some other manufacturers do, because we allow gravity to do the work for us.
All field piping and wiring connections are conveniently located on the rear of each module.
Built-in control panel with microprocessor control simplifies installation and maintenance.
Safety shutdown for abnormal cooling water conditions is included in the logic of the microprocessor control.
The DOUBLE-EFFECT absorption cycle and forced-draft burner reduce fuel consumption and require less heat to
be rejected to the cooling tower, resulting in energy savings and a smaller required cooling tower size.
UL Listed in the USA and Canada.
Cabinets are UL50E Type 3R and are suitable for indoor or outdoor installation without modification.
Each unit is run-tested at the factory prior to shipment. The factory trims and balances the solution concentration so
you don't have to.
Needs no back-up power source to prevent crystallization during a power failure, as gravity alone can handle it.
