Our specialty heaters include flow-thru heaters and infrared heating lamps. Flow-through heaters are used to pump and heat large quantities of liquids in a laboratory setting. Infrared heating lamps have an incandescent light bulb that is used to create heat. Many heat lamps include a red filter to minimize the amount of visible light emitted. These products are considered sanitary heat exchangers; fast, economical alternatives to heating and cooling liquids without the use of a tank storage system.
