Frequently Asked Questions
What are the primary applications for this unit cooler?
This unit cooler is highly versatile and designed for use in ceiling-mounted refrigerators, flower preservation cold storage cabinets, standard display cabinets, and small cold storage units.
How does the hydraulic expansion process benefit heat transfer?
By utilizing a hydraulic press to expand the copper tubes into the fins, we establish a connection that is extremely tight, even, and stable. This eliminates air gaps and ensures optimal heat transfer efficiency.
What makes the installation and maintenance convenient?
The unit features a dedicated slot-type hanger for straightforward mounting. Additionally, all electrical wiring is routed and connected inside a single, centralized electrical box, simplifying maintenance routines.
How durable is the casing of the unit cooler?
The bottom shell and side panels are integrated and formed simultaneously during manufacturing. This construction offers superior structural strength, stability, and a clean, professional aesthetic.
Under what test conditions are the nominal capacities measured?
The nominal capacities are calculated based on standard testing parameters: an air inlet dry-bulb temperature of -18℃, an evaporation temperature of -25℃, and a refrigerant liquid temperature of 20℃.
