WITT
Heat Exchangers

WITT spray chiller BVKF  Tube and shell heat exchanger with minimum refrigerant charge and maximum operation safety.
	WITT spray chillers are used when cooling close to the freezing point is required the vessel should be cleaned due to a risk of fouling low temperature applications create high vapor volumes
Advantages at a glance: integrated surge drum low refrigerant charge (ca. 200g/kW) high heat transfer (up to 10 kW/m²) capable of very small temperature differences (< 1 K) best protection against freezing due to minimum evaporation once the pumps are stopped WITT oil recovery WOR prevents oil residue and ensures good heat transfer no gaskets between refrigerant and coolant good cleaning ability
Standard scope of supply Tube and shell heatexchanger with spray system and integrated surge drum and all required connections frost pipe or standpipe WITT-refrigerant pumps, incl. down leg frame with wooden support WITT oil recovery
Accessories (optional) HP float regulator HR standpipe with level indicator WITT maximum level switch NGX control unit

WITT fully welded plate and shell heat exchangers enable a fully hermetic execution of the refrigeration system.
WITT plate and shell heat exchangers are selected when: - coolants with high viscosity are used - low temperatures with no gaskets are allowed  - a very compact design is required - flooded operation is prefered
Advantages at a glance - fully welded execution without gaskets stands for unrivalled safety - Round design enables very compact construv´ction also for flooded operation - efficient heat transfer enables high capacities even at small temperature differences
- reduced refrigerant charge - many coolants possible Possible executions - flooded evaporator PVS incl. top mounted high efficiency surge drum and oil recovery - plate and shell heat exchanger for pump operation PVP - Plate and shell condenser PK - Thermo-Syphon oilcooler PÖ - othe plate and shell heat exchangers upon request Accessories (optional) - HP-Float regulator HR - stand pipe with level control - WITT maximum level switch NGX
