ActivCool DTS 5000 Series Cooling Unit logo

The DTS 5000 Series cooling units deliver reliable enclosure cooling designed to keep industrial operations running. LED status indication or an optional full digital display provides instant visibility, while a pre‑installed gasket enables fast, consistent installation. External access to major components improves safety by reducing exposure to energized enclosures and helps minimize service downtime.

Available in optimized capacities from 4,000-10,000 Btu/hr with Type 12, 3R, and 4X protection options, the DTS 5000 Series is built for demanding environments from factory floors to outdoor infrastructure. Low‑GWP R‑513A refrigerant supports compliance with evolving regulations, giving OEMs, integrators, and end users a future‑ready cooling platform that installs easily, integrates cleanly, and is simple to service.

DTS 5000 Series Cooling Units

The DTS 5000 Cooling Unit a closed‑loop, side‑mounted cooling family that prevents critical temperature fluctuations by sealing out ambient air and recirculating clean, cool air inside the enclosure.

Environmentally Friendlier

Comes standard with low-GWP R-513A refrigerant, meeting stringent environmental regulations and rated A1 (non-flammable) for safety.

Interface Options

Choose an advanced digital display for real-time insight or the clear LED status indicators are available.

Closed Loop Design

Designed to isolate the external ambient air from the internally conditioned air eliminating the risk of contaminants entering the cabinet.

Thermal Overload Protection

Compressor and fan motors are outfitted with integral temperature switches to shut down the unit in the event of excessive temperature.

Thermal Expansion Valve

Regulates the flow of refrigerant based on thermal demand for efficient performance over the entire operating temperature range.

Active Condensate Management

Condensation is a natural by-product of refrigeration. The heated condensate collection pan boils this off thereby eliminating the need for drain tubes and buckets. To conserve power, this heater only activates when necessary.

Ease of Serviceability

Critical components are serviceable from outside the enclosure, improving safety by eliminating the need to open the energized electrical enclosure.

Easy Installation

The unit is shipped with the gasket installed saving installation time.

Efficient Circulation

Large evaporator for increased airflow path especially critical in densely packed electrical enclosures.

Pressure Overload Protection

High pressure cutout switch ensures safety by shutting off the compressor in the event of excessive pressure appearing in the refrigeration circuit.

High Airflow 

Backward curve impeller fan provides high airflow in a long lasting, single bearing design. Outperforms typical two-bearing blowers with nearly twice the lifespan.

Hermetically Sealed Compressor

The absence of any refrigerant fill valves eliminates leak paths. Recharging is never needed. 100% cooling capacity efficiency is ensured.
