Application Options
Ice-Making with Hardwired Interface
Unit controls are factory set to handle ice-making for thermal storage application. An additional
temperature sensor, at the compressor discharge, enables full load operation of the chiller with
entering evaporator fluid temperature between 20°F (-7°C) and 65°F (18°C) with glycol.
High Ambient
The unit starts and operates from 32°F to 125°F (0°C to 52°C).
Low-Temperature Processing
An additional temperature sensor, at the compressor discharge, enables leaving evaporator fluid
temperature between 10°F (-12.2°C) and 42°F (5.5°C) with glycol.
Partial Heat Recovery with Fan Control
A supplemental brazed plate heat exchanger is mounted in series to the condenser coil.
Connecting piping and inlet and outlet water sensors are included. CH530 controls display heat
recovery inlet and outlet water temperatures and controls the fans.The heat rejection to the
partial heat recovery heat exchanger is not controlled. Flow and temperature variations through
the partial heat recovery heat exchanger will vary.The partial heat recovery heat exchanger is
typically used to preheat water before it enters a boiler or other water heating process.
Dual
High Head Pump Package
Pump package includes: two high head pumps,VFD, expansion vessels, drainage valves, shut-off
valves at entering and leaving connections.
The pump package is single point power integrated into the chiller unit power with a separate
factory wired control panel.The control of the pump is integrated into the chiller controller.The
CH530 displays evaporator pump starts and run-times. Freeze protection down to an ambient of
-20°F (-29°C) is included as standard.The cold parts of the pump package will also be insulated.
Designed with one redundant pump, the chiller controls both pumps through a lead/lag and
failure/recovery functionality.
A variable speed drive is installed in an additional panel to control the pump.The inverter is
adjusted upon start up to balance the system flow and head requirements.The purpose is to save
on wasted pump energy caused by a traditional balancing valve.
Buffer Tank (only available with pump package)
The water tank is factory-installed for easy installation at the building site.The tank is engineered
for continuous flow and is fully insulated as standard and is designed with freeze protection down
to -20°F (-29°C).The purpose of the tank is to increase the chilled water circuit inertia, which is
