Stainless Steel Heat ExchangersWelded end and primary seals on these stainless steel heat exchangers eliminate contamination. Removable access panels ease inspection and cleaning. High heat transfer effectiveness is produced by corrugating the heat transfer plates to achieve a sinusoidal wave pattern. The corrugated surface creates airflow turbulence as the air passes through the unit. Heat transfer is further enhanced by using a counterflow design. Plate sizes range from 12, 36, 42 and 48", with unit lengths of 50, 74 and 98". The design of the Series SP spaces the heat transfer plates 0.5" apart; the Series HP spaces the heat transfer plates 0.375". Maximum operating temperature is 1,200oF (649oC).

Protective Coating for Heat ExchangersSaekaphen protective coating can be used to completely line the interior tube surfaces of shell-and-tube heat exchangers. Coating reduces fouling and protects the tubes from corrosion caused by most chemicals and all cooling waters. The lack of fouling and corrosion reduces maintenance and replacement costs.

Heat-Pipe Heat ExchangerFor air-to-air heat recovery, dehumidification and indoor air quality applications, heat-pipe heat exchangers have coils made of rows of individual, sealed aluminum tubes. The tubes have 1" inside diameters with an integral capillary wick formed into their inside walls. The tubes have integral fins with 0.015" average mean thicknesses, which are extruded from the tube wall to ensure maximum heat transfer. The system is driven by the temperature difference between two airstreams. There are no moving parts and no maintenance or external power is required.

Industrial CoilsKing brand flat-plate fin coils intended for “air over fin” applications where heating, cooling or refrigeration is required. All coils employ heavy-duty materials and welded construction. Diverse product line allows industrial coils to be used in a range of industries. Hot water coils, due to the ability of the water to freeze, will generally be found in a reheat portion of a heating system. Normally this insures that air below 35oF (1.6oC) will not come into contact with the reheat coil at a temperature between 45 and 75oC (7 to 24oC). Hot water coils are typically located in duct work where zone heating takes place.

Hygienic Plate Heat ExchangersModel NR5 Easy Flow can provide up to a 20 percent increase in processing capacity, according to the company, as a natural successor to its Model R5. With the new design, the same frame will carry up to 20 percent more plates because of a thinner plate material. The super-hygienic heat exchanger is made of 0.6 mm 316 stainless steel, whereas traditional hygienic plates are 0.8/0.9 mm. Measurements are identical to the company’s existing hygienic exchanger, which means that old plates can be exchanged without modification, or new plates can be added in combination with a separator. The plate is 3A approved and can be used in the dairy, food, beverage and pharmaceutical industries.

Heat, Cool and DehumidifySeries C can be used to replace shell-and-tube designs that have high pressure drop and, consequently, high operating costs. The pressure drop on the air/gas cooler shown is 0.1 percent; the model it replaced was 2.4 percent. The lower pressure drop will save 50 hp, which translates into energy savings of approximately $23,000 annually. Unit is stainless steel and has a washable, metal prefilter ahead of the cooling core and a removable mist eliminator downstream of the core. It will cool 5,000 cfm at 12 psi from 250 to 65oF (121 to 18oC) using 55oF (12.7oC) cooling water.

Welded Plate Heat ExchangersRekugavo and Rekuluvo are designed for gaseous products, working according to the countercurrent principle. The heat transfer surfaces consist of two profiled plates with a high specific capacity and are assembled into self-supporting packs. Both gases flow through the plates in countercurrent flow and are separated from each other without leakage. Mixing of the two gas streams (and possible transfer of pollutants) is thus almost completely excluded.
