� Aluminium fins � Fin spacing: 4 mm � Tubes staggered in air-flow direction � Special copper tubes: Ø 12 mm � Schrader valve at outlet
The capacity specifications apply to R-404A.The cooling capacity ratings refer to an air inlet temperature differential derived from the difference between the air inlet temperature at the cooler tL1 and the evaporating tempera-ture to, dT1 = tL1 – to.
These conditions are marked with dT1 and comply with the requirements of EN 328 and the Eurovent certification.
Our Güntner Product Calculator design software provides you with a thermodynamic design with capacity specifications compliant with Eurovent. This program provides a safe and easy way of configuring a suitable switch cabinet containing the appropriate control and regulation components.
� Aluminium-magnesium alloy, powder-coated in RAL 9003 (signal white)
� Stainless steel brackets for ceiling mounting flush with upper surface of casing
� Electric defrosting for coils and trays, factory-fitted � Electric defrosting for coils and trays, in set for on-site installation
� Epoxy resin-coated fins
� Aluminium-magnesium alloy, powder-coated in RAL 9003, thermally decoupled, polyamide condensation water drain, G thread with flat sealing compliant with DIN ISO 228-1
� Inner and outer trays hinged and removable for easy cleaning
Quality standard for hygiene certified by TÜV SÜD: The units are easy to clean and are particularly suitable for foodstuff processing applications since they are also approved for all materials used in contact with food.
The operation of units below a cold room temperature of -25 °C requires a special design.
Please contact our Sales team for further information.
� Low-noise axial fans with two preset speed settings, wired as standard
� IP 54 in acc. with DIN 40050 � Temperature range: -30 °C to +40 °C � Protection guard in acc. with EN 294 � Internal motor protection � Thermal class 130 (B) � AC fan, 230 V, 1~, 50 Hz
The second stage of the ErP Directive requiring mandatory minimum efficiency levels for fans came into effect on 1 January 2015. The products affected include products with built-in fans whose optimum input power is higher than 125 W. Conformity with the ErP Directive is explicitly indicated for units designed with the Güntner Product Calculator (GPC).
