Dry Coolers Condensers Plate Heat Exchangers
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 legionaires 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).
