Th. Witt Kaltemachienfabrik GmbH - Distributor

Product Details:

Robust, Open Refrigerant standard pumps. Due tos the usage of flanged, normed motors, service is very convenient, which is of particular interest in remote countries. For the use with ammonia these pumps have very good operation characteristics.Since the pumps are capable to deliver vapour/liquid mixtures they are able of self-recovery.

Attributes:

• Stop/Return Valve ERA
• Filter KS
• Pressure gauge and many more

Application:

• Open refrigerant pumps of the GP series are suitable to supply evaporators from a central surge drum in the capacity range 1 to 16m³/h and a delivery head of up to 70m.

Additional Information:

• Delivery Time: 3 to 4 weeks

Product Details:

Wherever the hermetic execution of a refrigeration system is required, e.g. due to local regulations, Hermetic refrigerant pumps of the HRP series are your best choice.

Advantages:

• Good delivery properties even at fast pressure reduction
• Hermetic execution of the entire pumps design with integrated canned motor
• Maximum safety, since the stator housing withstands the high nominal pressure of the pump housing.
• Maintenance-free special bearings that are cooled by the delivered refrigerant
• Integrated, internal vent line to the suction side eliminates expensive external vent piping on site! (Except CO₂)
• No extra orifices required! (Except CO₂)
• Also suitable for CO₂ as refrigerant or evaporating coolant.

Additional Information:

• Port of Dispatch: HAMBURG GERMANY
• Production Capacity: 15000 PUMPS PER YEAR
• Delivery Time: 4 WEEKS
• Packaging Details: FULLY PACKED PIECES AVAILABLE EX STOCK.

Product Details:

High pressure float regulators offer a simple, mechanical solution to expand refrigerant from the high to the low pressure side.

Attributes:

• Refrigerant
• Condensing Temperature
• Evaporation Temperature
• Capacity

Advantages:

• Highest safety and no operation failures, because the High pressure float regulator acts solely mechanically.
• Simple and robust overall concept of the entire refrigeration system without the need of additional cables or controls.
• Efficient operation, because the refrigerant is passed from the internal float when needed. Therefore low condensing temperatures without additional controls can be realized.
• Due to an internal low pressure nozzle (except the HR1BW type) that connects the gas area of the inside with the outlet connection, a slight under pressure is present in the housing. Therefore it is possible to place the float regulator up to 3 m above and up to 30 m away from the condenser.

Product Details:

We are the Supplier of Canned Pumps.

Advantages are for example:

• The ability to deliver gas/liquid mixtures.
• Therefore the pump is not interrupting the constant flow when gas bubbles occur during switching compressors on or off or loading or unloading evaporators.
• Top mounted suction connection - Even during operation there is a chance that gas bubbles may form. These gas bubbles should rise unhindered to the surge drum. This is only possible if the suction connection is provided at the top!
• No further accessories are required, such as orifices or constant flow valves.
