REMOTE CONDENSERS CLV

Product catalog summary

Specifications:
The document details remote condensers featuring copper pipes and aluminum fins with high-efficiency pyramidal corrugation. The frame is made from galvanized steel, painted in RAL9016, ensuring durability and noise reduction. Standard fan motors operate at 400V - 3F - 50Hz, with options for 60Hz, and are protected with IP54. Capacities are tested under specific conditions using refrigerant R404a, with a standard design pressure of 30 bar, and options for 45 bar. Performance adjustments are possible using coefficients for temperature differences, ambient temperature, refrigerant type, and altitude.

External Frame:
The frame is constructed from galvanized steel and features high-type fan cowls for optimal performance and minimal noise.

Fan Motors:
Standard fans operate at 400V - 3F - 50Hz, with 60Hz options available. They have an external rotor, IP54 protection, and are highly efficient. Motors and fans are balanced both statically and dynamically.

Declared Capacities:
Capacities are tested according to ENV327, with ambient temperature at +25°C, condensation temperature at +40°C, and using refrigerant R404a.

Testing:
All coils undergo testing with dry air and are degreased. Standard design pressure is 30 bar, with options for 45 bar available.

Performance Parameters:
Various coefficients (K2, K3, K4, K5) are provided for adjusting performance based on temperature differences, ambient temperature, refrigerant type, and altitude.

Options:
Several options are available, including fan motor wiring configurations, speed regulators, inverters, EC fans, safety switches, and additional pressure sensors. Specific configurations like vertical air flow kits, anti-vibration supports, anti-hail protection, and special frame colors are also offered.

Quick Selection:
Condensers can be selected based on compressor type, cooling capacity, and working conditions using provided parameters and coefficients.

Procedures:
The adiabatic system includes a three-way electrical valve managed by fan control, which pressurizes the system when temperature or pressure limits are reached. The system automatically empties after each cycle, with piping and nozzles made from AISI material. The pump group provides a maximum pressure of 10 BAR for efficient water nebulization.

Standards and Recommendations:
The standard working pressure is 2.5 BAR, and the minimum required water pressure is 1.5 BAR. It is recommended to use hydrophilic fins to limit corrosion, and the water's pH should be maintained between 6.5 and 8.2. For operations exceeding 200 hours per year, water softening is advised, with hardness not exceeding 10°F.

System Components:
The adiabatic system PD is fully assembled and includes a water distribution system, plastic panels, and trays for water collection. The system is designed to drain completely after each cycle, ensuring maximum efficiency with minimal water flow. The UV disinfection system for water sanitization is available as an option.

Performance Data:
The document provides detailed performance data for various models of remote condensers, including fan numbers, capacity, air flow, power consumption, and nominal current. The data is based on specific standards (ENV327, EN13487, ISO 3744) and includes notes on dimensions and weight.

Options and Compatibility:
Various options are available for the systems, and compatibility with local installation rules should be checked. The document includes a list of available options and notes on specific configurations.
