Glass-Lined Shell and Tube Heat Exchangers

DDPS features two main types of glass-lined heat exchangers.

The EC-type exchanger is mainly used as a condenser.  In conjunction with our reactors, it is possible to make up distillation ranges of any composition.  Its design is plain and permits to achieve great exchange areas with a small bulk. The EC exchanger can also be designed to serve as a heater or an evaporator.

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

Model D Heat Exchangers

12_Semiconductor_Production_Plant_HEmaxh=168,maxw=250,h=395,w=585

Advantages

The Model D offers a roster of capabilities to meet high-corrosion, high pressure, full vacuum, high temperature process needs effectively.  It can cope with the most stringent demands for product purity, process versatility and ease of maintenance.

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.

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

Core-Therm Heat Exchangers

Advantages

The diffusion resistant Core-Therm tube plate with its integral support plate and the corrosion-resistant materials PFA and PTFE can be used at high pressures and also operated under vacuum. Silicon carbide heat exchange tubes meets all the requirements of an optimum HE tube because of its heat conductivity of 125 W/m²K and its high corrosion resistance.

Features

  • Constructed of glass-lined steel with silicon carbide tubes.
  • Single tube seal with double clamp rings
  • Diffusion-resistant tube plate
  • QVF single tube seal

QVF Borosilicate Glass Coil Heat Exchangers

moz-screenshot-24

Coil type heat exchangers are mainly used as condensers, coolers, or boilers. They can, however, be used for heat transfer between liquids and gases in general.

Features

The coil heat exchanger design is based entirely on glass. The coil is fused to the shell. Units are supplied in various designs.

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

Specifications

  • Heat exchange area from 0.2 to 15.0 m²
