Overview: The document outlines a series of dual flow industrial unit
coolers designed for brine systems, offering flexibility with 6 to 10 row options to optimize capacity and surface area. These coolers are suitable for applications in cold rooms with temperatures ranging from -10°C to -20°C.
Heat Exchanger Coil: The coil features high-efficiency corrugated 'TK' aluminum fins and 5/8” copper tubes, pressure tested to 30 bar to meet quality standards.
Series Specifications: The document details various series with specific fin spacing for different temperature ranges: BHT (4.5mm for 15 to 2°C), BFT (6mm for 2 to -10°C), BMT (8mm for -10 to -20°C), GHS/GHL (4.5mm for 15 to 2°C), and GMS/GML (7mm for 2 to -20°C).
Casing: Made of protected aluminum, the casing is designed for strength and easy interchangeability with different systems.
Fans: Models are equipped with double-speed three-phase fans with IP54 protection. GHS/GMS series use high-speed delta connection fans, while DHL/DML series use low-speed star connection fans. Single-phase motors are available upon request.
Selection Procedure: The document includes a method for selecting units based on conditions like air and refrigerant inlet temperatures, with charts for correction factors considering humidity and glycol concentration.
Example Calculation: An example illustrates the selection process, calculating nominal capacity and pressure drops for specific conditions, such as a 30 kW capacity and 0°C cold room temperature.
Specifications: Detailed tables list models with capacities, air and glycol flow rates, surface areas, fan details, defrosting methods, noise levels, and weights.
Sound Levels: Sound pressure and power levels are provided, measured in dB(A) at 5 meters, with tables for sound power spectrum and distance corrections.
Additional Features: Optional features include electric heating elements, increased defrosting, floor mounting feet, insulated trays, and stainless steel casings.
Technical Drawings: Drawings are referenced for models with 9 and 10 tube rows, showing intermediate support legs.
Applications: Suitable for industrial, brine, and ammonia applications, with series designed for each type, providing detailed technical information for model selection.
