Why Choose the nVent HOFFMAN BPT38 Vortex Thermostat Kit?
The nVent HOFFMAN BPT38 is a purpose-designed 3/8" Vortex cooler thermostat kit that automatically controls the supply of compressed air according to the temperature inside an electrical enclosure. Designed for compatible nVent HOFFMAN BP and HT Vortex coolers, it combines an adjustable thermostat with a brass solenoid valve to provide demand-based cooling instead of allowing compressed air to flow continuously.
When enclosure cooling is required, the thermostat controls the solenoid valve to permit compressed air to reach the Vortex cooler. When cooling is no longer necessary, the air supply is restricted. This thermostatically controlled operation helps reduce unnecessary compressed-air consumption and associated operating costs, particularly in installations where enclosure heat loads fluctuate.
The BPT38 operates from a 240 V AC, 50 Hz supply and its thermostat is factory set to 35 °C while remaining adjustable for different cooling requirements. Designed for BP/HT 4 × 30 and 4 × 40 Vortex coolers, the thermostat mounts through a 22 mm diameter hole in the enclosure wall or can be installed on the supplied internal mounting bracket.
Key Advantages
- Provides automatic temperature control for compatible Vortex coolers.
- 3/8" configuration designed for larger BP and HT Vortex cooler models.
- Limits compressed-air flow so that cooling operates only when required.
- Helps reduce compressed-air consumption and operating costs.
- 35 °C factory thermostat setting can be adjusted to suit the application.
- Ideal for installations where enclosure heat loads fluctuate and continual purge is unnecessary.
- Flexible mounting through the enclosure wall or on the supplied internal bracket.
- Supplied with thermostat, mounting bracket and brass solenoid valve.

Efficient Temperature Control for Vortex Cooling Systems
Vortex coolers use compressed air to provide effective cooling for electrical and electronic enclosures. Because producing compressed air represents an ongoing operating cost, continuously supplying air when cooling is not required can reduce system efficiency. The nVent HOFFMAN BPT38 addresses this by controlling the compressed-air supply according to the enclosure temperature.
The adjustable thermostat works with the brass solenoid valve so that compressed air is supplied to the Vortex cooler when cooling is required. This makes the BPT38 particularly suitable for industrial installations with varying thermal loads, providing a straightforward method of improving compressed-air efficiency while maintaining effective enclosure temperature control.
Typical Applications
- Electrical control panel cooling systems.
- Industrial automation enclosures.
- PLC and electronic equipment cabinets.
- Machine control enclosures.
- Temperature-controlled Vortex cooling installations.
