The APV Hybrid is a fully welded gasket free heat exchanger combining highly efficient plates and a strong vessel construction. The asymmetric and flexible design allows extremely low pressure drop if required.
The APV Hybrid is individually designed and manufactured according to the required capacity, and represents an optimal solution in terms of technology and economic efficiency.
* High efficiency
* High capacity
* Low pressure drop
* Extremely flexible
* Easy cleaning and inspection
* Low maintenance costs
* Space saving
Material:
Plates: AISI 316L or most alloys
Vessel: AISI 316L or Carbon steel
Temperature: -200 to 900 Deg.C
Pressure: -1 to 60 bar gauge
The APV Hybrid has been applied successfully in the following industries:
* Sugar
* Natural gas and petrochemical
* Heat and power stations
* Refrigeration and heating
* Chemical and pharamaceutical
The compact Maxchanger unit transfers heat in much the same way as the gasketed plate and frame heat exchanger, but does so without gaskets. This ensures greater compactness than a gasketed plate exchanger, and requires only 30-50% of space required for a shell and tube heat exchanger.
Extremely high "U" values and low pressure drops are a result of the unique geometry of its interspaces. The specially embossed dimples on each plate provide maximum pressure-resistant heat transfer contact points. This design allows the Maxchanger to be capable of running under high temperature/ high pressure applications.
Specially dimpled plates are rotated and welded completely together between end plates, and in alternate channels at the inlet / outlet ends and connections. This thoroughly seals the entire unit to prevent leaking or cross-contamination of hot and cold media.
Counter-current flow of fluids is achieved in all Maxchanger designs, providing a close temperature approach capability of less than 1C.
Channels formed between the welded plates and end connections direct the two heat transfer media counter-currently through alternate paths for immediate thermal response and maximum efficiency.
The Supermax all-welded plate heat exchanger incorporates the benefits of plate and frame exchangers without gaskets. The Supermax all-welded plate heat exchanger provides the thermal efficiency and compactness of a plate and frame unit under conditions that would ordinarily call for a shell and tube unit.
Designed for use with liquids, gases and two phase mixtures at pressures to 70bar and at temperatures up to 540C the Supermax unit works well with aggressive media, such as organic solvents, steam heaters and interchangers that are beyond the capability of a gasketed unit.
The unit features a plate side and a shell side, which offers high pressure ratings. It has alternating channels for hot and cold media, and can offer true counter-current or co-current flow.
Nozzle sizes up to DN300 can be accommodated on the shell side of the exchanger, offering higher steam and liquid flow rates. Nozzles on the plate side can be up to 100.
The Supermax unit can be fabricated from dissimilar metals when only one side will be exposed to corrosive conditions.
The Ultramax offers all the benefits of a plate-type exchanger but overcomes the limitations of gasketed models. It can operate at very high pressures and at low and high temperatures. The Ultramax can handle liquids, gases and mixtures of the two.
Special alloy construction is available, allowing it to be used with aggressive media.
Applications include: high temperature steam, amines, thermal oil, nitrogen, solvents, and other aggressive media not compatible with gasketed heat exchangers. Four-inch connections allow up to 400 GPM in a single unit.
Threaded, flanged, and sanitary connections make the unit suitable for a number of industries.
