What is energy efficiency inspection?
Our specialists and experts – not only from the areas of refrigeration technology and refrigeration, but also from the field of building equipment – perform energy audits at individual facilities, and inspections within the context of the German Ordinance for Energy Saving (EnEV) and of DIN V 18599.These inspections include measures for testing of components that influence the efficiency of equipment facilities – and for checking the dimensioning of these facilities with reference to the cooling demand of the building. The inspections especially entail the checking and evaluation of influences that are relevant for design of the equipment, especially changes in space utilization and occupation, times of use, internal heat sources, the relevant physical properties of the building, as well as the desired values requested by the user with respect to air volumes, temperature, relative humidity, operational periods, as well as tolerances – including determination of the efficiency of essential components.

What is assembly on site?
Larger DencoHappel units are delivered on site in separate pieces that need to be assembled on site to form the complete unit. Our service engineers are able to support you in transporting and assembling our products and installations on site. Due to our many years of experience we can perfectly judge the risks involved.
The actual assembly of the units can either be done by our qualified engineers our by your own assembly team under DencoHappel supervision. As you may expect from us, we continuously update ourselves with the latest technologies ensuring that the assembly on site is performed with the utmost efficiency.
By outsourcing your assembly on site to DencoHappel engineers you will ensure yourself of having qualified engineers on site who know the product well and who are experienced and specialized in ensuring that our units are assembled using the proper tools and sealing materials. This will result in air tight units with lower risks of performance issues once commissioned.

What is full system commissioning?
Time pressures during construction often mean that building services systems are not properly commissioned and so never give optimum performance.
The best option is to engage DencoHappel Service to commission your system at the outset. Alternatively, we can carry out retrospective commissioning.
The result will be a plant that operates to design specification and is fully able to meet the demands of the end user.
