Intertec has launched its new Multicool 1100 cooler, the first to feature GRP (glass reinforced polyester) housing that is inherently resistant to corrosion – most comparable products are contained in metal enclosures that are susceptible to this problem.
Offering 1100 watts of cooling power the Multicool 1100 is a completely self-contained module that mounts directly on the outside wall of the equipment cabinet. Typical applications include temperature regulation of field-based sample conditioning and process analyzer instrumentation, and cooling the type of small distributed electronic control and monitoring systems used in many civil engineering projects.
A key feature of the cooling unit is that there is no direct air path between the ambient environment and the inside of the equipment cabinet. The closed loop refrigeration system has two completely separate and thermally isolated compartments, one for its evaporator, the other for the condenser and compressor stages.
The evaporator is the only part of the system that is connected to the inside of the cabinet, via air ducts that are hermetically sealed to the cabinet walls, and employs fan-assisted air recirculation to maximise cooling performance.
Heat is extracted from the cabinet by air flow over the evaporator and transported to the condenser via refrigerant gas. The condenser is cooled by its own separate fan, with the hot air and waste heat from the compressor being exhausted direct to atmosphere.
Multicool housing is constructed from the same proprietary grade of GRP that Intertec uses for all its environmental protection cabinets and shelters. This inherently inert material is an excellent thermal insulator and impervious to most commonly-encountered corrosive chemicals.
It has a similar strength to stainless steel but is about 75 per cent lighter. The internal chassis and pipework of the cooling unit are made from corrosion-resistant 316 grade stainless steel.
Routine maintenance requirements are minimal – an automatic condensate drain is fitted as standard and the refrigerant is R134a. It operates directly from a single-phase mains supply and is regulated by a thermostat that measures the air temperature inside the equipment cabinet.
