| This type of device condenses a refrigerant with the outside air. The fluid comes from the compressor manufacturers of a refrigeration circuit, circulates inside the bank of tubes, initially cools, then condenses before it leaves in the liquid state. In certain circumstances, the industrial condenser can be designed to ensure supercooling of this fluid. |

The EVAP plus plate-type evaporator is a fully welded supplier of heat exchanger without any gaskets. Those areas of sugar factories where such industrial evaporators are used see a substantial improvement of productivity and capacity.
The complete plate pack consists of pressed, roller seam-welded stainless steel plates forming two separate flow chambers, i.e. one tube-shaped and one wave-shaped channel.
EVAP plus %u2013 In use worldwide The low weight and reduced space requirements of GEA Ecoflex plate-type falling-film evaporators open up new possibilities for plant designers and operating companies. Their competitive advantages include not only their higher K values and smaller temperature differences, but also their possible retrofitting into an existing Robert evaporator.
World wide are approx. 100 units, with more than 300,000 m² heat transfer area,
successfully employed - e.g.:
Suiker Unie, NL, 6,000 m² pre-evaporator
Hohenau Evaporator Station, A, 20,000 m²
R.T. Wanze Sugar Factory, B, 39,000 m²
Nordzucker Uelzen, D, the largest single unit with 8,300 m² |

In the food industry, in the organic and chemical industry, and for industrial wastewater treatment.
Some advantages of the rising-film SIGMASTAR®.
Superior product distribution due to the thermo-siphon principle. As product boils and rises in the tube, fresh product automatically rises to refill the tube. This distribution technique operates independently of the feed rate, allows a high degree of flexibility and the possibility of turn down.
Very short residence time; the product is in the SIGMASTAR® for less than a second. This is due to the short flow distance and the high product film velocity. This feature guarantees a gentle treatment of the product.
Low pressure losses across the tubes, a benefit of the short tube length.
High vapour velocity in the rising film, which allows the processor to achieve high concentrations and viscosity.
Clearly defined product flow path. There is no chance of local over-concentration.
High heat transfer co-efficients are obtained even when the feed temperature is lower than the boiling temperature.
Compared to other evaporizer systems less expensive for high grade materials of construction.
Easy assembly and dismantling. A change in the size of the heat exchange surface by varying the number of heat exchange plates makes it possible to create more compact systems. |

APV PLATE EVAPORATORS
During the plate evaporation process, liquid is pumped between thin plates with the heating medium on the mating surfaces. The product is then evaporated with the vapour generated forming a high velocity core. This expansion in volume causes a high-velocity, thin film on the heat exchange surface providing efficient heat transfer.
Plate industrial evaporators should be considered for applications that have:
* Capacities up to 27,000 kg/h water removal
* A need for future expansion
* Limited head space
* A particle size smaller than 600 Micron
APV Product Range:
* Rising/falling film plate evaporators
The original plate type evaporator.
* Falling film plate evaporator
Combining all the advantages of the original Rising/Falling Film Plate Evaporator with the added benefits of even shorter product residence time and larger capacities.
* Paravap
The APV Paravap is specially designed to process high solids concentrates or those having non-Newtonian viscosity characteristics.
* Paraflash
For products which tend to crystallize during concentration or those that contain a high percentage of suspended solids.
APV Plate Evaporators Features/benefits:
* Improved product quality.
* Higher product concentration.
* Low liquid holdup.
* Easily cleaned.
* Flexible capacity.
* Low installation costs. |

| Frick Shell and tube Condensers are available with a refrigeration capacity range from 10 tons to over 1000 tons. With the proper material selection, they can be applied to a multiplicity of refrigerants including R-717, R-22, and R-134a. Shell diameters start at 8 and go to 48 inches and larger. Bonnets ranging from single pass to 10 pass provide maximum selection flexibility. Multiple shell arrangements can be utilized to match large refrigeration systems. |
