HEAT EXCHANGERS HEAT EXCHANGERS models. The SM-07 has a maximum plate side nozzle size of The Standard SUPERMAX constitutes a welded pressure vessel of high integrity. The standard unit is not designed for access or cleaning by mechanical means. The Removable Core SUPERMAX exchanger (available as an option in all sizes) is fully accessible for inspection and/or mechanical cleaning by removing the cover plate assembly. A full-face, flat-flange gasket is installed between the plate pack assembly cover and the shell assembly flange. Exploded view of Removable Core SUPERMAX Shell & Plate...

The Multipass SUPERMAX offers multiple passes through separate plate pack zones on both the plate and shell sides, with countercurrent ow through both passes. The unit has two plate pack units separated by a special one-port divider plate that directs the ow from the rst pack into the second and changes its direction by 180°. Inlet and outlet ports are at opposite ends of the unit. The shell includes a special ow director that directs the shell-side ow through one plate pack and then the other. 1.2. Service Limits 1.2.1.

HEAT EXCHANGERS </\ HEAT EXCHANGERS To lift SUPERMAX Shell & Plate units, use the lifting lugs provided for that purpose on the top of the front and rear cover plates. Do not use the pulling lug on the removable cover plate (if installed) to lift the entire unit. Lifting the SUPERMAX exchanger using the lifting lugs. Do not lift the SUPERMAX by the inlet or outlet nozzles. WARNING: Never lift the exchanger by the nozzles or apply any forces to the connections while lifting. 2.2. Mounting And Flow Control Always follow generally accepted piping and equipment control practices. Observing the...

HEAT EXCHANGERS ¿\ HEAT EXCHANGERS 1. Consult Table 2.1. to avoid overloading nozzles during installation and in the completed configuration 2. Avoid long, straight piping runs in the inlet and outlet approaches. 3. Employ elbows and expansion couplings to accommodate thermal expansion, pulsation and hydrodynamic shock that could damage the exchanger or its nozzles. 4. Position pipe supports no more than 2 m (78 in.) from the connections to prevent stress on the connection nozzles. 5. For removable core models, plan for removal of the approach piping downstream of the shut-off valves to...

2. INSTALLATION (continued) 2.2.5. Vents And Drains Vents and drains are standard on multi-pass units and all units where the application involves gases, noncondensable gases, refrigerants or two-phase ow. In these applications, always connect the vent and drain couplings to the draining and venting circuits through valves. The vent valve should always be open, allowing continuous self-venting. Vapor Break Connections WARNING: Your SUPERMAX guarantee may become void if vents are not employed with channels involving uids that can generate gases, e.g., in most feed/bottom heat recovery where...

HEAT EXCHANGERS 3.1. Critical Operating Principles All operators should familiarize themselves with the following operating principles, which are critical in preventing damage. CAUTION: In steam applications, never leave the steam on with the liquid side turned off. Turn the steam tfj^first and on last. 1. Water hammer, if suspected, must be diagnosed and eliminated, or damage may result to the SUPERMAX. 2. Pumps should always be started against closed valves. 3. Valves must be set to open gradually. Sudden opening and closing of the valves will subject the exchanger to mechanical and...

HEAT EXCHANGERS </\ HEAT EXCHANGERS 1. When handling any cleaning solutions, closely follow the safety recommendations provided by the cleaning solution 2. Always wear protective goggles and rubber gloves. 3. When diluting acid, always add acid to water. 4. Do not use hydrochloric acid (HC1 or muriatic acid) for cleaning stainless steel plates. 5 • Caustic soda and concentrated nitric acid can cause serious injuries to skin and mucous membrane. The SUPERMAX Shell & Plate Heat Exchanger is engineered and constructed for many years of reliable performance. Some fluids under certain...
