DJ-7.1/40 40㎡ 9mm Fin Space 2Fan 380v Air Cooler Evaporator
The DJ-7.1/40, a core model of the DJ Series Evaporator, is a high performance Air Cooler Evaporator purpose built for commercial and industrial refrigeration systems. As a versatile Evaporator, the DJ-7.1/40 Air Cooler Evaporator serves cold storage, food processing, pharmaceutical preservation, and retail display applications. Every DJ Series Evaporator – including the DJ-7.1/40 – combines advanced coil geometry with optimised airflow to deliver stable cooling capacity from 5 kW to 150 kW. This Evaporator series is engineered to outperform generic units, and the DJ-7.1/40 in particular offers exceptional reliability as an Air Cooler Evaporator.
Energy Efficiency: TheDJ-7.1/40 Air Cooler Evaporator design uses staggered copper tubes and hydrophilic aluminium fins, improving heat transfer while reducing fan power consumption. This DJ-7.1/40 Evaporator achieves up to 18 % higher sensible heat ratio compared to conventional units. As an Air Cooler Evaporator, the DJ-7.1/40 minimises operating costs.
Robust Durability: All DJ Series Evaporator casings – including the DJ-7.1/40 – are galvanised steel with powder coating; stainless steel options are available for aggressive environments. The coil of this DJ-7.1/40 Evaporator can be epoxy coated to resist corrosion, making it a durable Air Cooler Evaporator for harsh conditions.
Service Friendly: Tool less access to fan motors and blades reduces maintenance time by 40 %. The DJ-7.1/40 Air Cooler Evaporator features pre wired terminal boxes for plug and play installation. This Evaporator model also offers easy servicing, and the DJ Series Evaporator range shares common spare parts.
Flexible Defrost: Choose electric or hot gas defrost on any DJ Series Evaporator, including the DJ-7.1/40. Smart defrost termination sensors optimise energy use for this Air Cooler Evaporator, ensuring the DJ-7.1/40 Evaporator maintains peak performance.
DJ-7.1/40 Application Scenarios – Where This Evaporator Shines
The DJ Series Evaporator – and specifically the DJ-7.1/40 Air Cooler Evaporator – is engineered for five primary segments:
Food Cold Stores (0 °C to +10 °C) – preserving fresh produce, dairy, and beverages. The DJ-7.1/40 Air Cooler Evaporator maintains high humidity and uniform temperature. This Evaporator model is a trusted choice for cold store operators.
Freezer Warehouses (−18 °C to −25 °C) – heavy duty defrost cycles with wide fin spacing prevent ice build up. The DJ-7.1/40 Evaporator performs reliably in blast freezing tunnels, and as an Air Cooler Evaporator it handles extreme loads with ease.
Pharmaceutical & Chemical Storage – precise ±0.5 °C control meets GMP standards. The DJ Series Evaporator, especially the DJ-7.1/40, offers hygienic drain pans and stainless steel options, making it a premium Evaporator for sensitive applications.
Industrial Process Cooling – for moulding, printing, or laser equipment, where the DJ-7.1/40 Air Cooler Evaporator provides rapid pull down with secondary coolants (glycol or brine). This Evaporator adapts to diverse process needs.
Supermarkets & Retail – low noise operation (<65 dB(A)) makes the DJ-7.1/40 Evaporator ideal for open display cases and back of house storage. As a quiet Air Cooler Evaporator, the DJ-7.1/40 enhances the shopping environment.
DJ-7.1/40 Distinctive Features – Advanced Air Cooler Evaporator Design
Optimised Airflow: Aerodynamic fan guide vanes ensure even air distribution across the coil, minimising temperature stratification and product dehydration. The DJ-7.1/40 Air Cooler Evaporator delivers consistent airflow, and this Evaporator design reduces hot spots.
Compact Footprint: Depth reduced by 15 % over previous models, allowing higher pallet density. The DJ-7.1/40 Evaporator can be ceiling or wall mounted with included bracketry. This Air Cooler Evaporator maximises usable storage space.
Smart Controls: All DJ Series Evaporator units, including the DJ-7.1/40, are IoT ready, supporting PLC integration and remote monitoring via built in sensors for superheat and defrost termination. The DJ-7.1/40 Evaporator thus enables intelligent cold chain management.
Corrosion Protection: Optional dip spin epoxy coating on the DJ-7.1/40 Evaporator coil extends service life in salty or acidic environments (e.g., seafood processing). This makes the DJ Series Evaporator a durable Air Cooler Evaporator for aggressive sites.
Multi Refrigerant Compatibility: TheDJ-7.1/40 Air Cooler Evaporator works seamlessly with R404A, R448A, R290, and R410A, with minimal piping modifications. As a flexible Evaporator, the DJ-7.1/40 adapts to any refrigerant strategy.
