Achieve optimum process operation & energy efficiency!

When it comes to optimum process operation and energy efficiency, the right heat exchanger can truly make the difference. Heat exchangers are at the core of almost any industrial and domestic applications, as they are designed to perform the heating and cooling operations. Their performance has an impact not only on the process operation, but also on energy efficiency and costs. The right heat exchanger will require low maintenance, helping you reduce on operating costs.

When selecting the right heat exchanger, one has to keep in mind criteria such as:

  • Technology: evaluate the technology available and find the equipment with the best impact on production, profitability, and efficiency;
  • Application;
  • Operating pressures and temperatures, including startups, shutdowns, and normal operating conditions;
  • Product properties such as the density, viscosity, fouling tendency, specific heat, or latent heat;
  • Accessibility for cleaning and maintenance;
  • Mechanical considerations, such as the material of construction, thermal stress, or impingement protection.

With energy costs increasing almost every day, energy efficiency is an aspect that can no longer be ignored.

Selecting the right type of heat exchanger can be a daunting task. There are many variables one needs to keep in mind in order to achieve optimum performance and avoid operability issues and equipment failure. How can you decide which type of heat exchanger is the right on for you?

Shell & Tube Heat Exchanger

Probably the best known and understood heat exchanger, shell & tube heat exchangers are popular for their versatility in terms of types of services. They cover a wide range of applications. Sturdy and trusted, they are known to withstand rough processes.

Plate Heat Exchangers

Equipped with plates with large surface areas, plate heat exchangers have the capacity to transfer more heat than shell & tube heat exchangers.

Air Cooled Heat Exchangers

An air cooled heat exchanger is a pressure vessel, which cools a circulating fluid within tubes by forcing ambient air over the exterior of the tubes. Because it doesn’t require an auxiliary water supply, air cooled heat exchangers are considered to be more environmentally friendly than shell & tubes or plate heat exchangers.

Custom Heat Exchangers

Mahan’s Thermal Products offers custom heats exchangers for different applications. We provide expert design, analysis, and verification for custom solutions.
