Insulation Jackets

We provide a wide range of insulation jackets which are supplied with integral heating cables. These units are manufactured to suit each individual application. They facilitate quick and easy removal of the complete assembly for maintenance. If required we can provide an integral heating cable is used to maintain the equipment at the required temperature, which may vary from freeze protection to high temperature process maintenance.

Available in a variety of shapes, sizes and configurations, our thermal insulation jackets  are wrapped around external pipework casing, valves or flanges to control temperature and maintain substance flow rate.

  • Each unit may be supplied with a trace heating power connection junction box or thermostat to provide temperature control.
  • The units may also be used within Hazardous areas, as all of the trace heating materials hold ATEX hazardous area approvals.
  • Temperatures range for freeze protection to 600C

Instrument Manifolds

To be able to supply complete manifold solutions it is essential that all components within that solution are designed to match each other. That is where Multi Instruments Instrumentation differs from its competitors, as all products and parts used within instrumentation assemblies are engineered, produced and tested in-house, making it a perfect fit. This means that you only need to deal with one supplier to get a fully engineered and documented solution to your manifold problems, which makes procurement and expediting a lot more efficient. You'll only deal with the best partner in the manifold solution business. A partner that is globally qualified for the job, having the European ISO9001, PED and ATEX certifications, the Russian GOST-R and Application Permits and CSA explosion proof certification for the USA and Canadian market.
