Product catalog summary

Overview: This document details the specifications and features of advanced radial unit coolers and brine coolers, focusing on their construction, components, and operational parameters for commercial and industrial refrigeration applications.

Specifications:

Heat Exchange Finned Coils: Constructed with copper pipes and aluminum fins featuring high-efficiency pyramidal corrugation. The frame is made of galvanized steel to prevent contact with copper pipes.
External Frame: Made from galvanized steel, epoxy painted RAL9016, with insulated plenum for optimal airflow and noise reduction.
EC Fan Motors: High-efficiency plug fans with composite wings, capable of high static pressure, featuring external rotor motors with IP55 protection.
Testing: Coils are tested with dry air and degreased, with a design pressure of 30 bar.

Construction Features:

Available in diameters of 500, 560, and 630 mm with inner-grooved copper pipes and aluminum fins.
Operating temperatures range from -5°C to +40°C, with options for lower temperatures available.
Units are ready for ceiling installation with pre-assembled drip trays.

Defrosting Options:

Includes electrical defrosting with stainless steel heaters, hot gas defrosting, and imbricated hot glycol defrosting.

Performance and Capacity:

Cooling capacities are calculated according to ENV328 with refrigerant R404a, with adjustments for different refrigerants and temperatures using coefficients K1, K2, and K3.
Example calculations are provided for determining required evaporator capacity under varying conditions.

Model Specifications:

Tables provide information on model configurations, including fan specifications, sound pressure levels, power consumption, and defrosting options.

Additional Options:

Includes safety switches, floor mounting supports, prepainted aluminum fins, and various defrosting and construction options.

Ordering Information:

Order codes specify fan connections, fin spacing, coil type, and other parameters.

Specifications for Radial Brine Coolers:
Focuses on models AR56_E_F Ø 560mm and AR63_F_F Ø 630mm, with capacity calculations based on a room temperature of 10°C and 85% relative humidity, using 30% ethylene glycol.

Procedures:
Outlines procedures for confirming dimensions and weights, which must be reconfirmed by the technical department. Floor mounting supports are available upon request.

Standards and Compliance:
Products comply with Italian and European laws and regulations. The warranty excludes defects from unauthorized repairs or improper use.

Warranty:
Onda S.p.A. offers an 18-month warranty from delivery, covering material and workmanship defects. Claims must be made within 10 days of receipt or discovery of defects.

Recommendations:
