Shell and Tube Heat Exchangers
Shell and tube heat exchangers provide a versatile alternative to coil-type heat exchangers. They were conceived as condensers, but they are equally suitable for heat transfer between two liquids or gases.

Glass-Lined Shell and Tube Heat Exchangers
Glass-Lined Shell and Tube Heat Exchanger Product Description
DDPS features two main types of glass-lined heat exchangers:
The ED-type exchanger is particularly suited for the heating/cooling of products, by means of the thermal exchange between one fluid and another. It is made up of easily interchangeable standard sections. The product-side connection is made with loose flanges, bolts and PTFE envelope gasket, and that on the jacket by welding neck flanges or threaded couplings with flexible metal tube. This exchanger has the following advantages:
- Ability to adjust the bulk to existing local conditions
- Increasing or decreasing the exchange area
- Large exchange areas
Glass-Lined Shell and Tube Heat Exchanger Specifications
- Pressures from full vacuum to 87 psi (5.8 bar)
Model D Heat Exchangers
Model D Heat Exchanger Advantages

Model D Heat Exchanger Features
At the heart of its toughness and versatility is a steel reinforced, glass filled PTFE tube sheet with individual tube rings for extremely reliable sealing and maintenance. Standard units are equipped with a carbon steel shell, glass tubes, PTFE baffles, and individual tube seals.Model D Heat Exchanger Specifications
- Heat transfer area from 40 to 505 ft²
- Pressure up to 90 psig (6 bar)
- Temperatures up to 350ºF (175ºC)
Options
- Single, double or triple pass designs
- Alternative MOC for bonnets, shell and tube

QVF Borosilicate Glass Coil Heat Exchangers
Glass Coil Heat Exchanger Product Description

Glass Coil Heat Exchanger Features
The coil heat exchanger design is based entirely on glass. The coil is fused to the shell. Units are supplied in various designs.Glass Coil Heat Exchanger Advantages
Turbulent flow is ensured even in the larger nominal bores since the coil layers are offset and fill the flow cross-section to a great extent. This creates the following advantages:- No possible leak between the shell and the coil, making the design ideal for GMP applications.
- Outstanding corrosion resistance
- No possible metal contamination, yielding the highest product purity.
- Suitable for direct installation into columns
Glass Coil Heat Exchanger Specifications
- Heat exchange area from 0.2 to 15.0 m²
