Outdoor Type 3R/4 Cooling Units
Features/Benefits:
Pfannenberg strives to provide a relatively maintenance-free
design for our customers. All our designs have additional
options including:
Filter Kits Option - for special applications like dogwood seeds
or desert sand that need an external filter to prevent clogging
of the condenser core.
Enclosure Heater Option - for special applications where
heating is required to control condensate or keep electronics
above a desired temperature range in cold climates.
Voltage Options - Many of our cooling units have been
designed for both 50/60 Hz applications as well as 400 or 460 V
operations with a simple jumper change in the e-box.
Wide Condenser Fin Spacing / Coated Condenser & Pipes
This filter-free design also reduces the amount of maintenance required by the
customer. A quick cleaning of the condenser is required less frequently verses the
competition's models, while capacity is not compromised by easy clogging of the
condenser core.
Rugged, Long-lasting Backward Curved Impeller Fans
Utilizing this type of fan, our cooling units can go twice as long before needing
service verses a typical blower style fan that has smaller, low-cost and high
maintenance bearings.

Switch Cabinet
Proper Long Internal Air Flow Paths
The backward curve fan also has a natural right angle air path that allows our cooling
units to capture hot air from the top of the electrical cabinet and deposit cool, dry air
to the bottom of the cabinet and underneath critical components on the panel.

Hermetically Sealed Refrigeration Circuit
Utilizing a maintenance free design, Pfannenberg implements a hermetically sealed
design that eliminates gasketed valves and the leak source for many other A/C unit
designs. Therefore, our cooling units do not need annual maintenance to determine
if the unit is properly charged with R134a refrigerant.
Standard Control Board
Controlling temperature and alarm setting via dip-switches, preventing airflow short
cycling, high pressure switch alarm, on/off control of compressor with built-in delay
timer and a LED lamp with four different flashing sequences. The control board is located
in inner air circuit for protection from heat and dirt.

Outdoor Cooling Units
DTS 3261 (NEMA Outdoor Type 3R/4)
Cooling Unit 7000 - 8500 Btu/h
• Large distance between intake and exhaust vents, safe circulation within the electrical
enclosure due to long passage of air, therefore hot spots are eliminated
• Maintains a UL Tested NEMA Type 3R/4 seal against enclosure
• UL 484 Listed, category ACVS, UL file #SA10300, CE approved for European use
• Maintenance-free design, filterless for most applications
• Powder coated steel cover for rugged environments, easily painted to
match enclosure or machine
• Condenser with 3 mm fin spacing, highly effective protection against strongly
contaminated and aggressive ambient air
• Uses Internal Standard Control (SC) board
• Active condensate evaporation system
• Utilizes a thermal expansion valve (TXV) to ensure maximum performance
over a broad range
