Since1973, CHESMONT Engineering has become a market leader in providing design, construction, installation and solutions for industrial process heating systems.  We provide cost-effective, high-performance systems for manufacturing and industrial plant needs.  The Company's success is founded upon the ability to recognize the challenges faced by our client's and develop new creative systems that offer unique solutions.  

Propane standby system with packaged air/gas blending system, including one 30,000 gallon storage tank.

 Standby systems allow natural gas users to obtain the most cost effective natural gas pricing available.


Our industrial process heating systems often work behind the scenes to enhance and improve the reliability of our clients' products and services.

Producing technical solutions, whether it be for propane standby systems and gas trains, or metal treating furnaces that form the foundation for our clients ultimate product, requires CHESMONT to become a specialist in our clients end-use applications. 

We make a conscious effort to hire experts out of the markets we serve to act as both consultants during the system development process, and as technical engineering support for our clients.  For example, we have Professional Engineers on staff who offer preliminary design and testing assistance, coupled with permitting documentation and on-site installation.  

We recognize that the ability to compete in today's marketplace requires a focused knowledge of our client's needs.  This separates us from the companies who focus solely on fundamental process heat skills.


At CHESMONT, our first and foremost goal is to satisfy all of our clients.  Our mission statement emphasizes our search for excellence and our continual quest for improvement.  We will honor the commitments to our long-term partnerships with clients for the mutual benefit of both parties.

  What is Propane?  

Liquefied petroleum gas (commonly called LPG or LP-gas) is a mixture of several hydrocarbon gases. Propane and butane, used separately or in mixtures, are the principal LP-gases. They are either extracted from natural gas or produced as a result of processing crude oil at refineries.

Propane is the LP-gas most widely used in the U.S. At normal temperatures and atmospheric pressure, it exists as a vapor.  Producers convert propane to a liquid by a combination of moderate pressure and cooling. This greatly reduces space requirements, since approximately 270 gallons of propane vapor can be converted to one gallon of liquid. Moderate pressure holds the propane in liquid form until needed. A specially designed pressure vessel is necessary to maintain this pressure.

LP-gas has been a common fuel in homes and businesses since the early 1920's. Engine fuel use of propane dates back to the 1930's.

    Characteristics of Propane   

Propane has a number of unique  characteristics which increase its usefulness and value as an energy source. At the same time, these characteristics require that you respect the product to assure your safety.

Propane can be liquefied at ordinary   temperatures with moderate pressures.

As a liquid, propane is easily transported and stored.

Propane burns cleanly and has a high heat value.

Propane is not poisonous.

Propane is colorless and odorless in its natural state. A foul smelling odorant is added to help detect leaks.

Propane liquid is extremely volatile and will vaporize quickly if spilled.

Propane vapor is heavier than air and can accumulate in low spots.

Propane vapor will diffuse very slowly into the atmosphere unless assisted by strong wind currents.

Propane vapor leaking into the atmosphere cannot always be detected by the eye.

One gallon of propane liquid will produce about 270 gallons of propane vapor in the air.

One gallon of propane liquid will produce about 10,000 gallons or 1,300 cubic feet of a combustible propane-air mixture in the atmosphere.
