Air-conditioning and Process cooling

Chilling, air-conditioning and ventilation. An increasingly relevant topic. Our comprehensive portfolio of mobile cooling offers you the best available. For example, mobile split air-conditioning units for cooling server rooms or replacement cold water for process cooling. Suitable accessories such as ventilation units, mobile pump units or plate heat exchangers round off the portfolio.




Mobile air-conditioning units are especially well suited to rapid, flexible deployment. The compact size of these appliances makes them simple to handle and quick and easy to set up.

Chilling units are the main products in our rental range for cooling purposes. These environmentally-compatible air-cooled chiller units are ideally suited to industrial and process cooling applications.

What is rental refrigeration?

This concept refers to the rental of air conditioning units for the industrial and commercial sectors. These units are used in planned or unplanned situations (emergency, etc.). Mobile cooling systems are offered for both short and long-term rental. The range of services often ranges from mobile split air-conditioning units for cooling server rooms to mobile chillers for process cooling.

What are the advantages of renting mobile cooling systems?

Mobile cooling systems are often only used for a limited time. They are not in operation throughout the whole year. By renting a cooling system you have the possibility to remain economically competitive and to minimize risks. Your capital will not be tied up. For a defined period of time, you will get the highest technology and at the same time optimum performance with minimal energy consumption. Another advantage is that there are no maintenance costs. Storage costs are also eliminated. Your mobile air conditioners are only at your premises when they are in use. You have the possibility to plan the costs, while being sure to have the right technology for your needs.

Industriekälte: Was genau ist das und wo kommt sie zum Einsatz?

Industriekälte bezeichnet die Lieferung von Kälte und Abfuhr von überschüssiger Wärme welche in Produktionsprozessen anfällt. Große Anlagen der Lebensmittel- oder Fertigungsbranche müssen über den gesamten Zeitraum der Produktion mit Kälte versorgt werden. Gerade hier, in der Lebensmittelindustrie, ist es wichtig, dass die Versorgung mit Industriekälte zuverlässig verläuft. Ein Ausfall kann schwerwiegende Folgen auf Lieferketten und Produktion haben. Sollte es trotzdem zu einem Ausfall von Kältesystemen kommen, kann HOTMOBIL schnell und leistungsstark helfen: Mit einer Vielzahl mobiler Klimageräte und Kälteanlagen liefern wir mobile Industriekälte.

Renting a cooling system: What costs should I expect?

The rental costs incurred depend on various factors. First of all, the rental costs are calculated based on the days in which the mobile cooling systems are in use. The kW power also plays a role here. Further costs are those for transport and commissioning. It is advisable to define in advance the duration of use, so that costs can be determined more precisely. More information is available here.

In which areas is rental refrigeration used?

Rental refrigeration is gaining in importance in more and more sectors. It is often used for cooling server rooms or for process cooling in combination with mobile chillers. Rental refrigeration is becoming increasingly important also for air conditioning at events. The cooling of tents or halls guarantees comfort for the guests and planning security for the organizer. In the industrial sector, rental refrigeration is particularly important if significant cold chains fail. Also in emergency situations, renting a cooling system represents a solution that can be quickly and easily implemented. This allows you, for example, to cover further demand peaks when your existing cooling systems are already used at their maximum capacity.


Mobiles Klimagerät ohne Abluftschlauch

Ein mobiles Klimagerät ohne Abluftschlauch, maximaler Komfort bei gleicher Leistung. Klingt zu schön um wahr zu sein? Ist es leider auch. Eine mobile Klimaanlage ohne Abluftschlauch gibt es nicht. Es ist physikalisch nicht möglich, denn die Wärme muss transportiert werden. Es ist eine Wunschvorstellung, dass ein Raum mit einer Klimaanlage ohne Abluftschlauch vollständig und leistungsstark gekühlt wird. Solche Geräte sind als Luftkühler zu bezeichnen. Sie bringen aber nicht ansatzweise die Leistung wie ein mobiles Klimagerät. Wer den Raum jedoch trotzdem leistungsstark kühlen will, der sollte zu einem Klimasplitgerät wie dem COOLSPLIT MSG 4 greifen. Hier sorgt ein externer Verflüssiger für maximale Flexibilität bei hoher Leistung. Das mobile Klimagerät kann ohne Probleme auf Rollen den Raum wechseln und per Infrarot-Fernbedienung bedient werden.
