1:1 reproduction of your heat exchanger
Series and customer-specific furniture air cooler
The storage and display of food in the retail and catering sectors could not be more diverse and at the same time more demanding. Hygienic requirements, the correct temperature control and air humidity, as well as energy-efficient operation meet the most diverse refrigeration unit designs, from meat and sausage counters to refrigerated counters in the catering trade. Together with you, we develop customised heat exchangers for your refrigeration requirements in terms of performance, dimensions, refrigerants, corrosion protection, material combinations, as well as optimised tube and fin geometries. Either standard or system-specific as a system solution.
We gladly offer you the 1:1 reproduction of heat exchangers from refrigeration furniture that is still intact.
The UT / FK / GS / V is used in these areas of application
Commercial refrigeration
The use of refrigerated furniture, such as freezers, meat and sausage counters, refrigerated display cases, bar counters, etc., is very broad. Whether it's a butcher's shop, bakery, petrol station, restaurant or supermarket - every retailer has its own requirements to ensure optimum product quality. One thing is always in the foreground: reliability in refrigeration technology when it comes to failure safety, hygiene or energy efficiency. Roller is the specialist for air coolers, evaporators and heat exchangers for the commercial sector.

Types of corrosion protection
The heat exchangers can be equipped in a variety of corrosion protection types
Corrosion-resistant aluminium (AlFe1,5Mn)
fins are standard at Roller and can be used for long periods in slightly aggressive ambient air
2-component lacquer
with an even coating of the entire surface offers excellent protection, e.g. in sausage refrigerated counters.
Tin-coated copper tubing
has an additional layer of tin and offers extra protection against corrosion of the copper core tube
Gold lacquer fins (epoxy)
is a vinyl-based epoxy resin coating and offers increased protection against slightly aggressive substances, such as cleaning agents, vinegar,..., and supports simplified cleaning.
Copper fin
offers increased protection when storing salty foods
2-component lacquer
with uniform coating of the entire surface provides very good protection when storing open food in refrigerated cabinets

Furnature air cooler - Fa. Ott-Ladenbau
Shopping behavior has changed significantly in recent decades, also in food retailing. The customer wants to be attracted by an appealingly arranged range of products. The display of fresh goods in chilled furniture, such as meat, sausage or bakery cabinets and refrigerated shelves, as well as display vitrine is demanding. The cooling cabinets, which are adapted to the specific room situation, must also meet the highest demands in terms of cooling capacity, humidity level, quality and materials. For the construction of individual cabinets, company Ott relies on static air coolers from Roller, which are manufactured for a precise fit.
