Liquid-to-Liquid Cooling Systems

LCS20™ liquid-to-liquid cooling systems have cooling capacities up to 20 kW.

Lytron’s LCS20 is an excellent solution for high heat-load or high ambient temperature applications where chilled facility water is available.

LCS20 Features

  • With 20 kW of cooling, our LCS20 provides over three times the capacity of a comparably-sized recirculating chiller.

  • Integrated PID controller intelligently varies the facility water flow rate through the heat exchanger to achieve ±0.5°C temperature stability.

  • Isolated process cooling loop protects your equipment from facility water contaminants. It also eliminates the risk of condensation near your equipment if the facility water is below the dew point.

  • Very few moving parts makes the LCS20 inherently reliable and quiet. The only components requiring power are the pump, motor, and controller, so it is also extremely energy efficient.

  • ITSNA tested to UL 61010A-1 and CE certified

Cooling System LCS Options


Protection Options

External flow valve: HIGHLY RECOMMENDED. A manually adjustable globe valve installed on the back of the chiller in parallel with the chiller coolant supply/return.
Benefit: Allows the operator to control the flow rate to the application. As the external flow valve is opened, more of the flow bypasses the application.
External pressure relief valve: A manually adjustable pressure relief valve (50 to 100 psi or 0 to 50 psi) installed on the back of the chiller in parallel with the chiller coolant supply/return.
Benefit: Allows the chiller to continue to run and maintain temperature if the flow to the application is interrupted. When flow to the application is stopped, the pressure relief valve opens and bypasses flow to the chiller’s return. It can also be used to prevent the chiller supply from exceeding a predetermined pressure setting.
5 micron coolant filter: Externally mounted on the supply from the chiller.
Benefit: Filters process coolant being supplied to the application, protecting equipment from blockage or damage due to particulate buildup and extending pump life.

Special Applications Features

Heater: Submerged 2,000 Watt electric resistance heater with built-in over temperature shut-off (non-adjustable).
Benefit: Allows chiller to reach elevated set points faster (useful for applications in cold start-up situations or where the coolant set point is frequently cycled). This feature does not extend the coolant temperature range of the chiller.
Internal insulation package: Insulated tank, pump head, and coolant lines.
Benefit: Eliminates condensation forming on the components in contact with the fluid when operating chiller at set points below the ambient dew point.

Fluid Compatibility Features

Deionization Package: Externally mounted DI cartridge (no indicator light) on the return to the chiller.
Benefit: Filters ions from coolant to maintain a fluid resistivity level between 1 and 3 megohm/cm by partial flow through the resin bed. This feature does not include a resistivity indicator light. High purity plumbing is recommended with the DI water cartridge.
High purity plumbing: Includes nickel-brazed evaporator and nickel-plated or nylon fittings compatible with DI water. Not compatible with brass pumps.
Benefit: All wetted materials are fully compatible with DI water to prevent component corrosion.

Cooling System LCS Controllers

Controller Option & Functionality

Digital temperature display: Easy-to-read display in either °C or °F.
°C/°F toggle: Enables temperature display to be viewed in °C or °F.
Over-temperature indicator: Alerts user that the coolant temperature is over the user’s defined set point limits
Calibration offset: Allows temperature display to be offset to represent the temperature at a different point within the cooling circuit
Low level indicator: Alerts user that the coolant level in the reservoir is at a critically low level (approaching the level of the pump’s suction line).
Low flow indicator: Alerts user to a lack of coolant flow.
Analog output: Allows user to monitor pump discharge temperature remotely
