Ammonia (R717) Chillers custom engineered to your industrial process specifications

Ammonia refrigeration is at the core of our business. For 40+ years we have serviced, engineered, and designed ammonia refrigeration systems of our clients.

All of our ammonia systems are designed and build to Industry Standard and Codes, including ASHRAE, NFPA, UL, NEC, and IIAR.

Ammonia has been the refrigerant of choice for large industrial system for decades due to low lifecycle costs peace of mind knowing it will never be phased down or out. Ammonia is a natural refrigerant!

When to Consider an Ammonia (R717) Chiller?

Ammonia is an efficient refrigerant that can be used in a wide range of industrial process temperatures. For example, Tempest has designed -40F systems for Spiral Freezers, 0F systems for Ice Rinks, and 50F systems for Industrial HVAC

Tempest has designed ammonia systems ranging from 20 to 300-Tons on a single skid. 

Many refrigerants are currently on phase down and phase out lists due to the environmental regulatory landscape. Ammonia is a natural refrigerant that has been around since the beginning of refrigeration and will continue to be around for years to come. It is considered a natural refrigeration, offering low global warming potential (GWP) and Ozone Depletion Potential (ODP) properties. It’s considered to be one of the most environmentally friendly refrigerants on the market. 

Ammonia has excellent thermodynamic properties, which allow it to absorb and release heat more effectively than many other refrigerants. This results in lower energy consumption for cooling processes. Due to its high efficiency, ammonia-based systems require less electricity, resulting in lower operating costs

If your facility has ammonia already on site for other processes or if you already have a Process Safety Management (PSM) program in place.

5 Benefits of an Ammonia Chiller

Energy Efficiency

Excellent thermodynamic properties which results in lower energy consumption. Generally considered 15% more energy-efficient than HFC systems.

Environmentally Friendly

Ammonia is a natural refrigerant. It does not contribute to ozone layer depletion (ODP) or global warming potential (GWP).

Cost Effective

Low refrigerant cost and high energy efficiency combine for a lower lifecycle cost of ownership.

Industrial Usage

The thermodynamic properties of Ammonia make it a great low temperature option. It is used in a variety of industrial markets.

Proven Track Record

Ammonia refrigerant has been used for over a century. It will not be phased down or out.

Why can you trust an Ammonia Chiller from Tempest

Given our 40+ year track record of servicing, designing, and building Ammonia Chillers we’ve learned how to manufacture these systems for serviceability and SAFETY.

Tempest chillers are designed and built to ASHRAE, NFPA, UL, NEC, and IIAR standards and codes. We use only industrial components, which are skid mounted on heavy duty steel frame. Our refrigerant piping is fully welded. We can include ammonia leak detection systems and an ammonia dispersion tank for high pressure release.
