The Convenience of Cabinet Cooler Systems

Cabinet cooler systems from Pelmar Engineering provide a low-cost and reliable way to cool and condition electronic control panels. A cabinet cooling system incorporates a vortex tube to produce cold air from compressed air, with no moving parts. The cold air source provided by cabinet coolers stop cabinets from overheating and prevents ingress of contaminations such as dust or moisture.

Why Choose the Cabinet Cooling Systems

The vortex electronic cooler keeps electrical and electronic enclosures cool, clean and protected; they are also a low-cost alternative to expensive, high-maintenance air conditioners. Today’s small, compact multi-function electronic controls and programmable logic controllers are overly sensitive to both contamination and heat.

Smaller cabinets make temperature control difficult and increase vulnerability to premature failures. Excessive heat causes digital displays to misread, it drifts the control, and the breakers may trip below rated loads. This leads to productivity loss because of machine shutdowns.

The vortex air conditioning coolers maintain a slight pressurization in the cabinet to keep electrical and electronic components free from contamination. These cabinet air conditioners ensure that the cabinet’s environment is controlled to maintain enclosure temperatures within a specified temperature range.

Unique Features of Cabinet Cooling Systems

The vortex tube is at the innermost part of the cabinet cooling systems. The cold air that is produced by the vortex flows into the cabinet through the bulkhead fitting and is then ducted to a known problem component or to the center of the cabinet. The hot air created by the opposite end of the vortex tube flows to the atmosphere through a silencer.

The vortex tubes incorporated in the cabinet cooling systems are amazing and constructed of stainless steel. Stainless steel is the appropriate material to be used because it’s not vulnerable to wear, corrosion, and is oxidation resistant; this assures their durability and a maintenance-free operation.

Cabinet air conditioners are engineered and manufactured to endure the most difficult of environments and applications. The compact cabinet cooler can be installed in minutes through a standard electrical knockout. NEMA 12, 4 and a 4X cabinet cooler that match the NEMA rating of the enclosures are available in many cooling capacities for both small and large control panels.

A properly sized and well-designed cabinet cooler system with appropriate thermal management will definitely yield numerous advantages. Some of the benefits include extended life, optimum component performance, as well as efficient operation.

Usage Instructions

It is imperative that one be careful not to oversize the unit. A cabinet air conditioner with too large of a capacity for the application can result in freezing of the evaporator cells. The voltage supply must also be stable for the system to achieve an optimum performance. Moreover, the electrical enclosure should be sealed properly to prevent humidity and outside air from entering the system For more information, visit Pelmar Engineering.
