Guntner Products

Guntner U.K supplies finned and plate heat exchangers mainly for building services (HVAC) and refrigeration industries. Our range of products for Building Services (our main line of business in U.K.) consist of:

Dry Coolers

These are finned heat exchangers used to reject heat from air conditioning plant chillers etc. They cool the water/glycol mix in a closed circuit by passing ambient air over the finned surfaces. Dry Coolers are mainly used in lieu of wet systems i.e. as a replacement to cooling towers.

Dry Coolers come in various shapes and sizes from the small 1m length to a truck size and from 20 kW to 20,000 kW heat rejection capacities when used in multiples. They are preferred by most consultants and end users due to their low height - low noise - ease of use reduced pay back, high efficiency and due to virtually non-existent maintenance costs.

In addition they have no legionairres risk. All dry coolers are suitable for outdoor applications. Special centrifugal one’s are designed for use indoors and in plantrooms.

Air Cooled Condensers

These are finned water exchangers designed to reject heat to ambient from refrigerants being discharged from refrigeration compressors or chillers. They are supplied mainly to O.E.M. and chiller manufacturers to become part of their package. They also come in various shapes and sizes and their main applications are for low noise, low height or limited space projects. Condensers with axial fans are usually installed outdoors where as centrifugal fan condensers are suitable for indoors.

Fan Starter/Temperature Control Panels

With majority of dry coolers and condensers we provide unit mounted control panel to ensure:

• Smooth head pressure control for condensers.
• Smooth temperature control for dry coolers.
• To run fans at fixed speed, two-speed or variable speed configuration.
• All controllers (whether for fan cycling or variable speed) are manufactured by Guntner to the latest I.E.C. rules.
• Controllers are designed for flexibility and for "Free Cooling" use of the dry coolers as well.

Hybrid/Adiabatic Dry Coolers/Condensers

Where space and operating conditions are extremely limited, we can fit sprays to our heat exchangers for enhancing the heat transfer at specific times of the year. Mainly summer operation and are suitable for limited applications only.

Hybrid coolers are a very special category and are of high capital cost. They are used mainly at Car production plants and with absorption chillers for high duties and where space is at a premium. They operate as cooling towers during the summer as dry coolers at all other times but consume water at a fraction of the cost of a cooling tower.

Plate Heat Exchangers

Plate Heat Exchanger (P.H.E.) as the name implies is a composition of several embossed plates positioned next to each other with the heat exchange taking place from cold fluid being circulated on to the warm fluid circulated (and vice versa). This type of P.H.E. is referred to as a fluid to fluid heat exchanger.

Other versions of Plate Heat Exchangers include being used as evaporators (low pressure/low temperature refrigerant to chill water) and condensers (high pressure/high refrigerant to condenser water).
