Product Line

Solitherm is Seifert Systems' line of six air conditioner series for cooling applications. 
These are designed for indoor and outdoor, recessed and external mounting, top mount, rack and tight space applications.

Seifert air conditioners meet UL type 12, 3R and 4 standards. Units meeting UL type 4X are also available. Cooling capacities range from 1,000 BTU/hr through 21,000 BTU/hr – depending on the series.

Seifert thermal controls and accessories are designed to fit and work with our products as described in the product table. They include filter media, filter holders, NEMA 4X covers, temperature controller, mounting kits, condensate kits and more.

Our thermoelectric air conditioners can operate effectively in environments which are dusty and oily and where temperatures may vary from -4°F to 149°F. They can be used for both indoor and outdoor applications. All thermoelectric coolers comply to UL type 4X. Depending on the cooling capacity our thermoelectric coolers are available with AC or DC voltage.

Our StripLite LED enclosure lights have been specifically designed for illuminating control cabinets. They are available with an integrated on/off switch or motion sensor. Mounting is based on magnetic clamps and requires literally no installation. These lights are designed to be daisy-chained together for additional illumination.

Seifert air to air heat exchangers are designed to meet all industry standards. The functional principle of an air to air heat exchanger is quite simple. The heat exchanger core transfers the heat from the internal circuit to the ambient circuit through an aluminum surface, so there is no direct contact or mix between the internal and external air. 

They comply with the NEMA and IP requirements. Learn which is the best match for your application on our heat exchanger overview page.

Filter fans are non-active-cooling accessories for electrical enclosures and control cabinets. They are the simplest cooling method, provided that the temperature of the ambient air is lower then the cabinet air. Our exhaust filters are also available in EMC tested versions.

Cabinet heaters form part of our thermal management solutions. Temperature differences in cabinets, mostly in outdoor applications, often result in humidity and condensation which may cause function failures and corrosion. The use of the appropriate heating unit for your cabinet can eliminate these problems.
