Turflow Heat Exchangers

Description

The Turflow heat exchanger range is a shell & tube design

consisting of straight corrugated tubes within a shell. The tubes

are secured at either end of the shell by fixed tube sheets.

The corrugated tube design promotes increased turbulent flow

conditions to provide the Turflow’s high heat transfer efficiency.

The shell incorporates a bellows type expansion joint that ensures

thermal stress does not damage the heat exchanger. The shell is

also fitted with drain and vent connections. The heat exchanger is

a gasket free design constructed wholly from stainless steel.

Normally the heated fluid will flow through the tubes and the

heating medium will be in the shell; both countercurrent and

concurrent flow paths can be accommodated, inclusive of

horizontal or vertical installation.

Standards

Turflow type heat exchangers fully comply with the requirements

of the European Pressure Equipment Directive 97/23/EC and

carry the CE mark when so required. All units are supplied with a

Declaration of Conformity.

Certification

A manufacturer’s Hydraulic Test Report and Material Certification

documentation is available on request.

Note: All certification/ inspection requirements must be stated at

the time of order placement.
