General Information
The Need for Environment Control
With wide spread use of micro-electronics in today’s control systems, temperature management takes on a new priority in
order to ensure steady and reliable performance. The maintenance of a correct operating temperature may combine both
cooling and/ or heating inside an enclosure which can protect against costly down time and system failures.
General Selection Considerations
Cooling
Conditions
Maximum desired enclosure
temperature is 10°F or 5°C
above maximum outside ambient.
Solution
Advantages
Oversize the enclosure. Easy to implement, no maintenance.
Maintains NEMA rating of the
enclosure.
Install ventilation
Economical solution, very little
louvers.
maintenance, easy to implement.
Install filter fans.
Less expensive than air/refrigeration
systems. Relatively high amount of
heat removed, some termperature
control by using thermostats.
Easy to install, small power
consumption, temperature control via
thermostat. Maintains NEMA rating of
the enclosure.
Easy to install. Temperature control
via factory installed thermostat.
Removes large amounts of heat.
Maintains NEMA rating of enclosure,
dehumidifies enclosure air.
Disadvantages
Dissipates small amount of heat.
Larger enclosure size takes up more
space.
Dissipates limited amount of heat.
Dirt, oil or fluids could enter the
enclosure. NEMA rating is affected.
Must maintain filters. NEMA rating
can be affected. Limited use in hostile
environments such as chemical
applications.
Must maintain filters.
Use an air/air heat
exchanger.
347
Climate Control
Maximum desired enclosure
temperature lower than
maximum outside ambient.
Use an air conditioner.
Must maintain filter. Generally not to
be used when outside temperature
is below 59°F (15°) or above 130°F
(52°C).
Circulation
Conditions
Localized heat or 'hot spots'.
Solution
Install circulation fans
in the enclosure.
Advantages
Economical solution, no maintenance,
easy to install. Maintains NEMA rating
of the enclosure.
Disadvantages
Dissipates small amount of heat.
Heating
Conditions
Outside temperature is below
minimum allowable equipment
operation range.
Condensation occurs.
Solution
Heat with radiant
heater.
Heat with radiant
heater to maintain
temperature above
the dewpoint.
Advantages
Economical power consumption.
Reliable, can be temperature
controlled.
Economical power consumption.
Reliable, humidity can be controlled.
Disadvantages
Consumes energy, takes up internal
panel space.
Consumes energy, takes up internal
panel space.

Sizing an Air Conditioner
Sizing an Air Conditioner
The proper selection of an air conditioner is determined by the following steps:
Step 1)
Step 2)
Step 3)
Step 4)
Internal heat load quoted as Watts that must be dissipated.
The exposed surface area of the enclosure.
Temperature differential required between maximum inside temperature and maximum outside ambient.
Final calculation of the above.

1 Watt = 3.413 BTU/H
Determine the internal heat load
(in Watts) that must be dissipated.

Capacity Required
BTU/H. Capacity Rating.
The DTS/DTT offering is available in the most popular selection of cooling capacities, sizes, voltages and mounting configurations. Available
capacities range from 1,200 to 24,000 BTU/H in both side mounting and top mounting models. All models use powerful radial fans for maximum
air circulation inside the enclosure in ambient temperatures of 125°F (+52°C). Models from 2,000 BTU/H capacity are equipped with thermal
expansion valves for optimal use of the evaporator heat exchange surface under all operating conditions. For additional protection of the
compressor motor, these valves are supplied as standard with Maximum Operating Pressure control devices (MOP). For energy conservation,
the use of hot gas bypass valves is limited to the unloaded starting and control of large compressors from 8,000 BTU/H upwards. All air
conditioners were developed, designed and subject to final inspections in accordance with international standards.
