RECESSED COOLING UNITS
Our DTI 6401 series cooling units have about 2x greater cooling capactity than the DTI 6202/6301. These cooling units also utilize a long internal air path to capture heat above the components and provide cool air below. These units are ideal for mounting on a cabinet door and are partially recessed for space restricted installations. Housing: galvanized sheet steel. Cover: electrostatically powder coated RAL 7035 (light grey)
ERP Efficiency Certified
As a component of the Kyoto Protocol to reduce carbon monoxide emissions, the European Energy Related Products (ERP) Directive includes an efficiency rating for fans. Pfannenberg proudly utilizes components which adhere to these requirements for up to 43% energy savings and operating costs reduction.
High Airflow Backward Curve Impeller Fan
Provides high airflow in a long lasting, single bearing design. Outperforms typical two-bearing blowers with nearly twice the lifespan.
For space restricted installations, ideal for door mount.
Thermal Overload Protection
Compressor and fan motors are outfitted with integral temperature switches to shut down the unit in the event of excessive temperature.
Pressure Overload Protection
High pressure cutout switch ensures safety by shutting off the compressor in the event of excessive pressure appearing in the refrigeration circuit.
Closed Loop Design
Designed to isolate the external ambient air from the internally conditioned air eliminating the risk of contaminants entering the cabinet.
Large distance between intake and exhaust vents for efficient air circulation and elimination of hot spots.
Utilizes HFC-free R134a refrigerant versus a blended refrigerant for easier service and minimized negative impact to the environment.
Energy Efficient Hibernation Mode
When cooling isn’t necessary due to equipment shutdown or cold weather conditions, the unit conserves energy by turning fans off – except for periodic cycling for circulating air within the enclosure.
Three-phase 400/460 VAC powered units are protected from phase mis-wiring.
Maintenance Free, Filterless Design
The wide fin spacing is less susceptible to clogging from dirt buildup which can cause the unit to work harder and hamper efficiency.
For visual temperature monitoring.
Easy Installation and Maintenance
Tool-free spring plate design keeps the unit safely in place and allows mounting by 1 person in less than 3 minutes with 55% lower mounting costs. Direct access to the PCB and the fans means 80% shorter repair times.
Hermetically Sealed Compressor
The absence of any refrigerant fill valves eliminates leak paths. Recharging is never needed. 100% cooling capacity efficiency is ensured.
Active Condensate Management
Condensation is a natural by-product of refrigeration. The heated condensate collection pan boils this off thereby eliminating the need for drain tubes and buckets. To conserve power, this heater only activates when necessary.
Thermal Expansion Valve
Regulates the flow of refrigerant based on thermal demand for efficient performance over the entire operating temperature range.
