4 Introduction
The Koolant Koolers Indoor Industrial Process Chiller is a single ‐ circuit, single reservoir chiller designed to
supply coolant to the Hypertherm Plasma Cutting System. Heat removal from the plasma cutting system to the
chiller is facilitated through heat exchangers in a closed ‐ loop fashion using an air ‐ cooled refrigeration circuit.
The chiller is capable of steadily supplying coolant with tight temperature tolerances over a varying and dynamic
range of cooling capacity requirements. The chiller features:

Scroll Compressor

Proven reliability

Low noise

Process circuit regenerative turbine pump

Highly reliable (no sliding components)

Optimized for high pressure circuits

Recirculation circuit centrifugal pump

Moderates the return coolant temperature from the plasma cutter prior to passing through the
brazed plate heat exchanger

Highly reliable (no sliding components)

Variable speed condenser fan

Minimizes acoustic noise

Improved energy efficiency

Manages refrigeration suction pressure under low ambient temperatures

Continuous coolant reservoir level sensing

Provides low reservoir warnings

Prevents pumps from running dry

Process & recirculation flow sensing

Protects pumps from running dry

Supports proper setting of throttling and relief valves

Refrigeration pressure and temperature sensors

Enable the suction and discharge conditions of the refrigeration circuit to be monitored by the
controller

Enable the controller to calculate superheat and subcooling conditions to support remote
troubleshooting

Remote monitoring and control capabilities

Plug ‐ and ‐ play communication via Modbus Ethernet

Built ‐ in webserver for data logging and remote monitoring
