Heat exchangers
With design simulation through PV Elite and HTRI thermal software you can rely on Smardt Pressure Vessels UK selecting the most efficient and cost-effective solution for your application.
Advantages of Smardt Shell & Tube Heat Exchangers Versus Plate Heat Exchangers
Shell & Tube Heat Exchangers have been the backbone of heat transfer for many years.
Having been used over the decades, a reliable source of data and wealth of knowledge is readily available, making them a popular choice in many applications.
Manufactured from a wide variety of materials such as stainless steel, carbon steel & cupronickel in a number of designs these heat exchangers offer a wide scope to the designer of the heat transfer system.
Benefits:
They can be designed and manufactured to bear pressures in excess of 200 bar and temperatures from -100°C to +500°C.
They have no dimensional limit
They can be used in all applications.
Pressure loss is at a minimum and can be maintained at a minimum in line with the process purpose.
They can easily be disassembled and assembled back for maintenance, repair and cleaning.

How Smardt Pressure Vessels UK can help?
- All heat exchangers have capacity limits.
- Careless sizing of evaporators leads to needless performance problems.
- Under sizing can lead to insufficient cooling and insufficient compressor operation.
- Oversizing can lead to control valve hunting, poor performance, oil logging and refrigerant slugging.
Smardt Pressure Vessels UK can design and manufacture the right heat exchanger for your application.
Evaporators
Suitable for Ammonia, Hydrocarbons, CO2 and low GWP
- Direct Expansion Evaporators (DX)
- Flooded Evaporators
- Shell & Tube – Fixed Tubesheet or ‘U’ Tube Bundle Shell and Coil
Condensers
A Condenser is properly sized when its capacity to transfer heat from the system is equal to the cooling load, plus the extra heat generated by the work of compressing the gas. This total is called the Total Heat of Rejection.
Suitable for Ammonia, Hydrocarbons, CO2 and low GWP
- Shell & Tube
- Shell & Coil
- Marine (Cupro-Nickel)
- Stainless Steel
Shell and Coil Heat Exchangers
We can manufacture any type of coil to suit the application. All we need is the duty and the inlet out temperature required.
- Closed Flash Economisers/Intercoolers
- Desuperheaters
- Suction Accumulators with boil off coil
- Stream Condensation/Cooling
- Liquifiers (CO2, Hydrocarbons)
- Solvent recovery
