TEC-1612 Thermoelectric Gas Cooler

TEC-1612 Thermoelectric Gas Cooler

The Apex Instruments TEC-1612 Thermoelectric Gas Cooler, a robust single-stage gas cooler, effectively removes condensate and delivers dry gas to the analyzer. Designed to be mounted on a wall or in a rack, the TEC-1612 gas cooler can also be converted to a portable unit within its frame. It is designed to be used as a stand-alone unit or coupled with our ACC-1610 Air-Cooled Condenser.


The TEC-1612 has a single easily removable condenser encased in an insulated aluminum block and cooled by two state of the art thermoelectric heat pumps. Dual high-output axial fans are coupled with the latest thermosiphon heat exchangers to support the thermoelectric units and allow the gas conditioner to operate in a wider range of ambient conditions. The condenser is designed to effectively separate condensed moisture from a sample gas, while the integrated peristaltic pump ensures rapid removal of condensation from the system.

The TEC-1612 is the perfect choice for your modular gas sampling system. We listened to feedback and strive to deliver an effective solution that is lightweight and rugged.

Pinnacle Cooling Technology

Water vapor is removed by cooling the sample gas to a constant dew point with the Apex Pinnacle Heat pump. The Pinnacle assembly in the TEC-1612 utilizes two thermoelectric modules, which operate on the Peltier effect.

The Pinnacle heat pump is easy to service and designed to withstand heavy use.

Stainless Steel Condenser

The condenser is fabricated from 316 stainless steel and can be treated with a variety of coatings: silicon, polyfluorinated, silane; polar or non-polar. The micro annular flow channel provides maximum condensation efficiency with minimum contact time. The single condenser setup improves response time.

Pinnacle Cooling Unit

The Pinnacle heat pump unit includes a highly conductive aluminum block fitted with two rugged thermoelectric modules, a stainless-steel condenser, a high-efficiency heat exchanger, exhaust fan, and a PID temperature controller.

The heat pump uses an extremely reliable rugged solid-state thermoelectric module (TEC) and a low-resistance heat exchanger with a copper base and heat pipes with high thermal conductivity for removing heat from the hot side of the TEC and dispersing the heat to the surrounding environment via the exhaust fan.
