Explosion-Proof Cold Controls

Flammable and Dangerous

While newer refrigerants over much lower Global Warming Potentials (GWPs), they are often less resilient to flammability and explosion.

This increased volatility poses a safety risk, particularly if a leak allows the refrigerant to mix with the surrounding air. Refrigeration-related explosions can occur when these gases are ignited from an electrical spark, such as those generated when a relay switch starts the compressor, or when a thermostat switch mechanism cycles the compressor on or off. The explosion, which can occur within or around the refrigeration system, can cause significant damage to equipment and property, injury and even death.

The Solution

Robertshaw electromechanical cold controls curb that problem. These controls eliminate the risk of flame due to gas leakage through a combination of sealed enclosures and internal design features. They provide you and your customers with explosion-proof protection and peace of mind.

Robertshaw Explosion‑Proof Cold Controls are ideal for:

• Liquid Coolers
• Bottle Coolers
• Ice Makers
• Refrigerators
• Display Cabinets
• Upright Freezers
• Chest Freezers

Environmentally Friendly. Simple. Flexible.

Consumers demand safety while also demanding products with environmental benefits. Robertshaw Explosion-Proof Cold Controls do both. Plus, integrating them into existing thermostat OEM designs is simple.

Lower GWP (Global Warming Potential)
Newer regulations require the “next generation” of refrigerants. These lower-GWP alternatives are better for the environment, but they increase the risk of flammable gases and explosions. Robertshaw’s Explosion-Proof Cold Controls eliminate that problem.
Easy Transition
Swapping current thermostat components for Robertshaw Explosion-Proof components is straightforward and fast, with no other additional changes required to the equipment design.
Multiple Options
Choose from four different Robertshaw Explosion-Proof Cold Control options — RCX, TXV, K Controls and ACE — depending on the temperature requirements’ required voltage, amps and other specifications.
