Product catalog summary

Flow Principle of a Plate Heat Exchanger
The plate heat exchanger operates by transferring heat between two fluids through a series of corrugated metal plates. These plates create channels for fluid flow, promoting turbulence and efficient heat transfer. The fluids flow through alternate channels, achieving counter-current flow for maximum efficiency.

Standard Design
The exchanger consists of a pack of corrugated metal plates with portholes for fluid passage. The plate pack is compressed between a fixed frame plate and a movable pressure plate using tightening bolts. Gaskets seal the interplate channels and direct fluid flow. The number of plates is determined by flow rate, fluid properties, pressure drop, and temperature requirements. Connections are located on the frame plate or both frame and pressure plates if multiple passes are needed.

Typical Capacities
The exchanger can handle liquid flow rates up to 5 kg/s (80 gpm), depending on media, pressure drop, and temperature program. Plate types include TL3B, TL3P, and TL3BD (double wall plates), with frame type FG.

Working Principle
Channels formed between plates allow alternate media flow, with heat transferred through the plates. The corrugation supports the plates and enhances turbulence, improving heat transfer efficiency.

Standard Materials
Frame plates are made of mild steel with epoxy paint. Nozzles are stainless steel or titanium. Plates are made from stainless steel alloys (316, 304), titanium, Alloy 254 SMO, or Alloy C-276. Gaskets vary by plate type, including materials like Nitrile, EPDMP, HNBR, and Viton®G.

Technical Data
Pressure vessel codes include PED, ASME, and pvcALS™. Mechanical design pressure/temperature for FG is 1.6MPa/180ºC or 150 psig/356ºF. Maximum heat transfer surface is 10.9 m² (117.3 sq.ft).

Connections
Connections for FG PED and pvcALS™ are 1¼” pipe, thread ISO-R 1¼”. FG ASME uses 1¼” pipe, thread NPT. Dimensions for type TL3-FG are H: 790 mm (31.1"), W: 190 mm (7.5"), h: 61 mm (2.4").

Quotation Requirements
To obtain a quotation, provide flow rates or heat load, temperature program, physical properties of the liquids (if not water), desired working pressure, and maximum permitted pressure drop.

TL3 Flow principle of a plate heat exchanger Plate heat exchanger Applications General heating and cooling duties. Standard design The plate heat exchanger consists of a pack of corrugated metal plates with portholes for the passage of the two fluids between which heat transfer will take place. The plate pack is assembled between a fix frame plate and a movable pressure plate and compressed by tightening bolts. The plates are fitted with a gasket which seals the interplate channel and directs the fluids into alternate channels. The number of plates is determined by the flow rate, physical properties of the fluids, pressure drop and temperature program. The plate corrugations promote fluid turbulence and support the plates against differential pressure. The plate and the pressure plate are suspended from an upper carrying bar and located by a lower guiding bar. Connections are located in the frame plate or, if either or both fluids make more than a single pass within the unit, in the frame and pressure plates. Typical capacities Liquid flow rate Up to 5 kg/s (80 gpm), depending on media, permitted pressure drop and temperature program. Plate types TL3B, TL3P TL3BD, double wall plates Frame types FG Working principle Channels are formed between the plates and the corner ports are arranged so that the two media flow through alternate channels. The heat is transferred through the plate between the channels, and complete counter-current flow is created for highest possible efficiency. The corrugation of the plates provides the passage between the plates, supports each plate against the adjacent one and enhances the turbulence, resulting in efficient heat transfer.
