Air Cooled Aftercoolers for Compressed Air
The compressed air discharged by an air compressor contains a considerable quantity of water in the form of vapor. If this is not removed, much of it will condense in the distribution system and cause expensive damage to all the equipment and processes which use the air. An efficient airblast aflercooler is an effective means of eliminating a significant proportion of the water contained in the compressed air. The new AF range of airblast aflercoolers is the result of a development program which builds on the worldwide success of the existing range for even greater efficiency, reliability and economy in operation.

In Boiler tubes, when water is evaporated to steam are called Steam Generating Tubes. These Tubes also form the Walls of the Boiler and are hence called Water Walls or Water Wall Panels. These Tubes have very complicated shapes to allow Inspection openings and burner throats and fabrication require intricate binding on CNC programmable bending Machines and checking on 3D layouts.
M.J.Patel can supply these tubes with ends swaged/reduced to smaller diameters or expanded to higher diameters. Ends can be supplied fully ground and annealed to facilitate Expansion or bevelled to weld to Header Stubs. The Water Wall Panels are High frequency tube to tube welded and then bent on Panel Bending Machines or the Gas tight panel can be made by welding Fins to tubes using Low Temperature Automatic Welding Machines using CO2 and Filler wires.

Brazed plate heat exchangers are made up of an individually defined number of high-quality embossed special steel plates that are permanently joined in a special vacuum brazing process using either copper or nickel. They are hermetically sealed without gaskets and can therefore handle the highest operating pressures and temperatures.
During assembly every other plate is rotated by 180 degrees in the plane to produce two separate flow channels in which the products involved in heat transfer flow in counter flow. The plate contours generate a highly turbulent flow allowing efficient heat transfer even at low volumetric flows. This prevents any soiling of the heat exchanger and non-flow zones are completely separate.
The surface of the brazed plate heat exchanger is utilized almost completely for heat transfer, and this makes the unit extremely space-saving and cost-effective.

The Copes-Vulcan VO-76 is especially well suited for high pressure and temperature service (e.g. ANSI 1500 and above). It is particularly adaptable where custom fitting to new or existing piping is a problem. The VO-76 provides alternatives where limited space or changes in header diameter are factors.
Features:
- The VO II offers extremely fine control and exceptional turndown that is limited only by the rangeability of the coolant control valve itself. Typically the unit can achieve a rangeability of 100:1 when matched with a Copes-Vulcan control valve fitted with Cascade trim design.
- Due to excellent mixing of vapor and coolant, control is possible throughout the entire operating range to within 5 °F (2.5 °C) of the set point, which can be as close as 10 °F (5 °C) above saturation.
- The coolant pressure, which is required at the inlet to the VO II need only be 5 PSI (0.35 bar) above the pressure of the vapor being desuperheated.
Since virtually all the desuperheating occurs within the body itself, usually no pipe liners or long downstream straight pipe runs are necessary.

Extruded finned tubes
At the heart of most Thermofin heat exchangers’ technology lies Thermofin’s aluminium extruded finned tubes, they are the lead actors on which rests the efficiency and longevity of our units. Their particular design (mono or bimetal) provides great resistance (fin stiffness) as well as exceptional heat transfer characteristics (longevity, temperature range). The mechanical bond joining liner tubes and aluminium wall insures no corrosion occurs between fin and tube, a key factor in permitting the delivery of the specified duty by your heat exchanger, it also offers superior durability.
Heat pipes
Based on Thermofin’s extruded fin tube technology, our selection of heat pipes is designed to suit the need of the Original Equipment Manufacturer. Whether they be bent in ‘U’ shape or equipped with end fitting to facilitate their filling, Thermofin’s heat pipe designs are devoted to match your thermal and geometrical requirements. Their superior thermal performance is partly linked to the fintube inside capillary surface, created during the tube manufacture, this surface promotes the refrigerant migration.

Gasketed plate apparatuses are heat exchangers with a modular design which are very flexible and can be easily adjusted. They are commonly used in commerce and industry. Corrugated plates are selected from the types / sizes available depending on the medium to be heated or cooled, where the medium's physical characteristics are of particular importance. The plates are then "assembled" into customised heat exchangers. Software is used to assist in the selection of type and size and greatly simplifies the listing of alternatives. Thermowave does however always use software developed in house to configure the apparatuses so that the latest advances in technology can be rapidly implemented. The ultimate goal here is to use our expertise and detailed knowledge to respond to requests from our customers and other interested parties, to allow in-house "know-how" to be assimilated and to make the software distinctive.
The usage limits of plate heat exchangers are often determined by the resistance of the plate and gasket material to the media in question. The 'database of practical knowledge' available within the company is indispensable at this point as is a fully functioning configuration programme.

Schmidt Gasketed Plate Heat Exchangers
SIGMA Plate Heat Exchangers utilize corrugated plates stacked between a fixed and a movable pressure plate. The corrugation patterns alternate for maximum operating pressures. As virtually all of the material is used for heat transfer, Plate Heat Exchangers can have large amounts of effective heat transfer surface in a small footprint. It is not uncommon that a Plate Heat Exchanger will have the same thermal capacity as a Shell & Tube five times larger.
The unique corrugation pattern pressed onto each Schmidt thermal plate produces the highest overall heat transfer rate by assuring highly turbulent flow and excellent fluid distribution across the entire surface. With high heat transfer rates and true counter current flow, Schmidt Plate Heat Exchangers economically handle close temperature approach requirements.
