LIQUID COOLERS FLV - PFLV

LIQUID COOLERS FLV - PFLV

Product catalog summary

Specifications:
All liquid coolers feature finned coils made from copper pipes and aluminum fins with high-efficiency pyramidal corrugation. The frame is constructed from galvanized steel to prevent damage and ensure durability. The external frame is epoxy painted in RAL9016, and fan cowls are designed for optimal performance and noise reduction. Standard fan motors operate at 400V - 3F - 50Hz, with options for 60Hz. They include an external rotor with IP54 protection and are balanced both statically and dynamically. Capacities are tested according to ENV1048 standards at specific temperatures using a water/ethylene glycol mixture. Coils are tested with dry air and have a standard design pressure of 10 bar. Performance coefficients adjust for temperature differences and altitude. Options include various fan motor configurations, speed regulators, and additional protective features. The adiabatic system requires a minimum water pressure of 2.5 bar.

Overview: The document details technical specifications for liquid coolers in the FLV and PFLV series, including model configurations, capacities, air flow, power consumption, and dimensions.
