Filtrine’s Explosion-proof Chillers Operate in Any Hazardous Environment

Filtrine explosion-proof liquid chillers are manufactured to ensure that no spark will be released from the electrical components of the chiller that could ignite gases, dusts or chemicals that may be present in the specified areas. Filtrine uses custom-designed enclosures, motors, switches and other electrical components which are connected by special wiring conduits. Explosion proof chillers are built to meet NEC Standards for Class 1, Divisions 1 & 2 and Groups B, C or D hazardous locations. The Filtrine Model XP chillers are designed for heat loads ranging from 2,000 – 300,000 BTUH with outlet temperatures ranging from 0°F to 90°F. All explosion-proof chiller components are contained within a single housing


Filtrine Constructs Each Chiller to Match the Customer’s Specifications

Filtrine works with equipment manufacturers, owners or engineers to ensure the chiller will provide the most efficient and effective equipment cooling in a package that also meets the site requirements.

All process chiller models are available in Closed Loop (PCP), Open Loop (POC) and One Pass (PC) configurations.

Filtrine Closed Loop Chiller Schematic

For PCP Closed Loop Models: The chiller pump pulls water through the chiller storage cooling tank (which provides close temperature control) and pushes it into the industrial process application. It recirculates the coolant at constant pressure and flow adjustable by a manual bypass valve. Because of its water saving features, this is Filtrine’s most popular chiller model.

Filtrine Open Loop Chiller Schematic

For POC Open Loop Models: The chiller pump recirculates the water from an open pool or sump through the chiller and back. An adjustable thermostat senses the temperature of the make up liquid, cycling the chiller storage cooling tank to ensure a constant temperature.

Filtrine One Pass Chiller Schematic

For One-Pass PC Models: The water inlet provides the pressure and flow into the chiller before being added as an ingredient or fouled by the product it is cooling. A high transfer immersion coil evaporator supplies maximum capacity at any flow rate with no pressure drop. The storage cooling tank design provides close temperature control without short cycling.
