Description

The circulation heaters of the AHPF series heaters are ideal for heating low flows of air, inert gas, water, or aqueous solutions. Applications include those where clean air is necessary, as in laboratories and environmental testing areas. The stream of air is heated by passing over an enclosed heated surface rather than directly over resistance elements. This method assures that no foreign matter will enter the stream of flow. The AHPF series is also used as a miniature circulation heater for small volume of liquids as in photographic developer solution, chemicals, dyes, and inks.

The Thermocouple “T” fitting AHPF-NPT12 can be used with the K-M-1-3-25-1/4NPT-GS-1 probe listed in accessories below to monitor the outlet temperature of the heaters.
