Filtrine Chiller Options & Accessories

Filtrine’s chiller engineering features include:

Energy Saving Design: Filtrine’s chiller design features the storage-method of cooling. Each Filtrine chiller has a chiller barrel that consists of a stainless steel storage tank with an immersed stainless steel evaporator. The capacity of the storage tank and length of the evaporator are sized to meet the heat removal requirements of the application. This takes advantage of the fly-wheel effect of cooling where the energy is stored in the coolant to produce consistent, reliable outlet temperature. Unlike most process chillers, the Filtrine chiller’s refrigerant circuit only cycles on when the coolant temperature in the tank needs cooling. This saves energy over conventional cooling systems.

Complete Temperature Control: Temperature adjustable within a range of 40° to 90°F (5° to 32°C) and will hold temperature within ±1.5°F (.8°C) of setting. (±0.5°F optional). If the heat load from the application swings large amounts, the chiller will deliver the coolant at a consistent temperature.

Condenser Options: Filtrine chillers are offered with the integral air-cooled, integral water cooled condensers or remote air-cooled condensers.

Coolant Loop Options: Filtrine chillers serve closed loop (PCP), open loop (POC) and single pass (PC) applications.

HFO Refrigerant: Eliminates use of ozone-depleting and high GWP (Global Warming Potential) refrigerant as per Montreal Protocol.

Welded Stainless Steel Cooling Tank: Recirculates clean coolant sealed from the atmosphere, eliminates bacterial build-up, evaporation and the need for feed tank. The tanks are designed with internal expansion space, so expansion tanks are not needed.
