Air cooler TE series

for enclosure air conditioningfor electrical cabinetcompact

Overview
Thermoelectric enclosure coolers remove heat around critical components to minimize downtime and component failure in small indoor and outdoor enclosures. These low-profile units use the Peltier effect to provide cooling or heating without refrigerants, compressors or filters, making them suitable for low-maintenance, low-noise industrial applications. Designed for partial recess mounting and flexible orientation.

Features

• Operates on the Peltier effect for cooling or heating by reversing polarity
• Contains no refrigerant — filterless and compressor-free design
• Low-maintenance filterless construction for demanding environments
• Suitable for indoor and outdoor enclosures with Type 12/3R/4/4X protection levels
• Prewired with a simple terminal block for straightforward DC wiring
• Available in shrouded and unshrouded variants as standard
• Operating temperature range: −40 °C to 55 °C (−40 °F to 131 °F)
• Partial recess mount; low-profile for vertical or horizontal installation
• DC operation for 24V and 48V applications
