Stationary Warm Air Heaters S / SC

Warmly recommended

Kroll's stationary warm air heaters of the S series are particularly suitable for the temperature control of large and high rooms, such as workshops, production halls, exhibition and trade fair halls, greenhouses or warehouses. Especially in the industrial/commercial sector, the demands on heating systems are high; trouble-free continuous operation must be guaranteed, the units should be designed to be as maintenance-friendly and energy-efficient as possible, and long preheating times must be avoided. Furthermore, people must not be disturbed, neither by draughts nor by high noise levels. With heating solutions from Kroll, you can be sure that you have made the right choice.

Ein Klassiker ist dabei der stationäre Warmlufterzeuger Typ S: Seit Jahren bewährt, tausendfach eingesetzt und in mehr als 20 Varianten zwischen 25kW und 600 kW Leistung und Pressung bis zu 1600 Pa verfügbar. Wer es ein wenig bequemer möchte, kann auf den stationären Warmlufterzeuger Typ SC zurückgreifen; durch integrierte Steuerung mittels Touch-Screen, automatischer Wartungsanzeige und integrierter Tag / Nachtautomatik ist maximaler Komfort zu jeder Zeit gegeben. Mit einer Leistungsspektrum zwischen 25 kW und 100 kW bleiben besonders in kleineren und mittleren Objekten keine Wünsche offen. Auch nachträglich lässt sich für mehr Komfort sorgen: Ein bereits verbautes Gerät Typ S lässt sich mittels Servicekit jederzeit auf Typ SC nachrüsten.

Since the units operate without an additional carrier medium, heat is immediately released into the ambient air and energy is saved. There are no limits to flexibility: Whether with fuel oil, liquid or natural gas operation, as a duct or stand-alone unit, horizontal or vertical, in fresh air, recirculated air or mixed air operation - the S series can easily meet your individual requirements in new and existing buildings.

Special accessories such as louvre controls, intake filters, automatic heating oil deaerators, etc., make it possible to solve any challenge according to requirements. Individually adapted duct systems can be used for warm air distribution in several rooms.

Die Warmlufterzeuger wurden nach aktuellen Anforderungen an Heizsysteme entwickelt und erfüllen in Kombination mit einem 2-stufigen Brenner die EU-Verordnung der ErP-Richtlinie 2021 vollumfänglich. Sie vereinen langjährig bekannte Kroll-Qualität mit moderner, energiesparender Technik für einen störungsfreien Dauereinsatz. Dabei können die Geräte ganzjährig betrieben werden: Im Sommer sorgen sie im Lüftungsmodus für frische Luft, im Winter sorgen Sie für angenehme Temperaturen und helfen dabei, Ihre Energiekosten zu senken. Gerade in großen, hohen Räumen ist die Kombination mit unserem Ceiling Fan DV is particularly useful and can provide you with further savings potential through heat recirculation.

We guarantee the quality of our products - As the first manufacturer in the heating and ventilation sector, we offer our customers a full 3-year manufacturer's warranty.
