Less cost layer by layer: Benefit from the expertise of our partner BASF SE. IS-Service uses this partner to provide coatings for individual heat exchanger plates and other components in line with your specific requirements. This adds genuine value, because it is an effective means of preventing the corrosion of lower grade stainless steels in all cooling waters, as well as in sea water.

The minimal deposit formation and the resulting reduced need for cleaning (often possible in a closed system using CIP), are other advantages of the procedure which significantly improve the service life of individual processes. Non-stick coatings will help you to save money and reduce your CO2 emissions! Because of this, non-stick coatings are a useful way of optimizing processes that affect the environment, in line with the future holistic approach under ISO 14001. 

Summary: Timely coating increases the service life of components and the return on your investment.

Ellehammer - Ejectors


Ejectors are assigned to the so-called motive media pumps. They represent a fluid-dynamic apparatus which is applied for delivering, mixing, dosing and also to generate a vacuum. Liquids or gases standing under pressure serve as motive media. Apart from liquids or gases, suction media can also be formed of fine or pulverous solids. ELLEHAMMER manufactures diverse constructional forms and their designations are derived from the media involved:

  • Liquid-Liquid Ejectors
  • Liquid-Gas Ejectors
  • Liquid-Solids Ejectors
  • Gas-Liquid Ejectors
  • Gas-Gas Ejectors
  • Gas-Solids Ejectors

According to the application case in question, a different designation other than used in the market can be utilised. For example, for liquid/liquid ejectors in shipbuilding one speaks of so-called bilge, ballast or stripping ejectors.

Or for liquid/gas ejectors, according  to function one speaks of liquid jet gas compressors,liquid jet vacuum pumps or also of liquid jet ventilators.

Important for all constructional forms of ejectors is that these do not possess any moving mechanical elements and therefore do not show corresponding signs of wear which would demand a continuous maintenance. This apparatus is practically maintenance-free.

The performance of this apparatus is influenced directly by the pressures prevailing at the connections and by the flow rates. It is, therefore, indispensable for an optimised performance
that an individual designing and manufacturing for the planned later application case is carried out.

Each application of standardised ejectors leads irrevocably to grave losses in performance and this is to be avoided at all cases.

Due to their individual manufacturing, ELLEHAMMER ejectors help to reduce consumption of operating power and therefore to minimise constructional sizes and pipeline cross-sections. The latter also includes further savings possibilities regarding the required pipeline fittings. Comprehensive information documents in the written form or as electronic data sets are  available. In case of a requirement, please do contact us directly.

It's a common issue: In large gasketed plate heat exchangers (PHE) with a high number of plates, the individual plates which are clamped together frequently get displaced in the frame. This is exacerbated every time the plate heat exchanger opens and closes, and ultimately leads to leaks and mechanical damage to the individual plates.

This happens because the suspension area for each plate is occasionally too small. This area is used to guide and fix each plate in the area of the upper and lower support rod. Once this area is damaged, the displacements increase exponentially every time the plate stack closes!

Cleaning & Re-gasketing

On-site cleaning (mobile / stationary):

We can provide the appropriate CIP cleaning system for your needs, whether mobile or stationary, with tank sizes ranging from 15 to 2500 litres. The pumps can be operated with 230V/50Hz and 60Hz or 110V/60Hz, depending on requirements. We provide the appropriate cleaning chemicals for all mobile and stationary CIP systems as standard, including a product and application description and the appropriate safety data sheet (in all EU languages) for your system, e.g. gasketed plate heat exchanger. This ensures effective cleaning without damaging your material.
