Product Design Options

Air Cooled Chillers

Air-cooled chillers are designed to remove heat from a process and discharge it to the ambient air. These systems are ideal for processes where facility water is unavailable or costly. Standard design parameters require adequate ventilation and an ambient air temperature between 5-35°C. High ambient models are also available.

Water Cooled Chillers

Water-cooled chillers are designed to remove heat from a process and discharge it to an auxiliary facility water supply such as a central chilled water system or cooling tower.

The facility water source does not need to be temperature controlled, however, water sources exceeding 35°C may require special design features. (See facility water requirement graphs)

These systems are easy to install and feature a small footprint, modular design, and quiet operation, with capacities up to 100kW.

Non-Refrigerated Heat Exchangers

Non-refrigerated heat exchangers are designed to remove heat from a process and discharge it to an auxiliary facility water supply such as a central chilled water system or cooling tower.

The facility water source must be at least 10°C below the process water temperature to provide a temperature differential (typically 10°C). Models offering smaller temperature differentials are available upon request. These systems are easy to install and feature a small footprint, modular design and quite operation. They require no refrigeration and are available with capacities of up to 150kW.

Specialty Fluids Chillers

Due to extreme temperatures, dielectric fluid requirements, or algae issues, many applications are best suited for a heat transfer fluid other than plain water. Through years of experience and close partnerships with the specialty fluid manufacturers, Lydall has become the leading manufacturer of highly engineered chillers for use with specialty fluids such as:

• Ultra-pure DI water
• Deionized water
• Water & Glycol mixtures
• 3M Fluorinert and HFE dielectric heat transfer fluids
• Dow Syltherm Silicone Oils
• Ausimont's Galden Fluids

Features

• Agency approvals-CE, NRTL, MET and Semi S2-0200 listings
• Small and large capacity units available (500W to 300kW)
• Wide temperature range –85°C to 200°C

Benefits

• Close partnerships with fluid manufacturers to help customers avoid common issues
• Leak free operation through the use of conservative solid plumbed coolant designs and magnetic drive pumps
• Lower cost of ownership- longer lasting DI cartridges and leak free fluorochemical units
