Seifert has recently expanded their line of control cabinet cooling units with the Progressive series air conditioning and Peltier thermoelectric coolers. The Progressive series features units with cooling capacities ranging from 1000 to 21,170 BTU per hour, with an operating temperature range of -40 F to 131 F (-40 C to 55 C). The Peltier thermoelectric coolers have cooling capacities ranging from 170 to 2730 BTU per hour and can work in temperatures ranging from -4 F to 149 F (-20 C to 65 C).
The Progressive series air conditioners are external mounted units that meet the standards for UL Type 12, 4, 3R and 4X. They can be used in outdoor applications as well as corrosive environments. These air conditioners can have a powder coated steel or 304 stainless steel housing. The controller is on the back of the unit so it stays protected inside the enclosure and can be viewed from inside the cabinet. The default cooling temperature is set to 95 F (35 C) and is adjustable between 68 F to 122 F (20 C to 50 C). Components are hardwired, so there are no extra cords or plugs that need to be dealt with. Filters are located at the bottom and can be accessed for replacement simply by unscrewing the bottom panel. They also feature a built-in condensate evaporation package, with a heating element underneath the drip tray, so they won't drip water.
Peltier thermoelectric coolers are solid state units, with no compressor and no refrigerant, so they can be mounted vertically or horizontally. Peltier coolers transfer heat between the internal and ambient heat sinks. A fan then helps dissipate the heat from the heat sink. They can be recessed mounted or externally mounted to the cabinet. External mount units have an added frame for installation. They have a 304 or 316 stainless steel housing and are filter-less for a maintenance free operation. Meeting the standards for UL Type 4X, they can be used for both indoor and outdoor applications. These all-electric coolers are intended for use with smaller enclosures. Peltier units can be used instead of a cabinet fan or also act as a dehumidifier. A thermostat should be used with most of the DC units to keep the fan from running constantly, while AC thermoelectric units have a thermostat built in. Separate condensate drain kits for the Peltier coolers are also available. The drain kit mounts to the bottom of the unit to catch the condensate and directs it to a single funnel.
The Peltier coolers can be ordered online or over the phone. Most of the Seifert Progressive air conditioners ship by freight, so please contact us for a quote.
