Evaporators TLE Serie

Product catalog summary

Technical Information
The TLE series shell and tube evaporators are designed for cooling water, liquid, or brine solutions in refrigeration systems and for producing hot water in heat pumps. They are compatible with refrigerants like HCFCs and HFCs, provided these are suitable for the materials used. The cooling capacity ranges from 130 to 1420 kW, with options for 1 to 4 refrigerant circuits. Water connections are typically vertical but can be customized.

Materials
The exchangers are made from high-quality materials that comply with European pressure vessel standards, including carbon steel and copper, with asbestos-free gaskets. Custom materials are available upon request.

Accessories
Optional accessories include mounting supports, counter flanges, and insulation.

Standards and Testing
Exchangers are pressure tested on both refrigerant and water sides according to THERMOKEY or other standards, complying with European safety codes. ASME standards are available upon request.

Working Limits
Design temperatures range from -10°C to +90°C, with pressure limits up to 3 bar.

Selection Recommendations
The fouling factor is important for selecting an exchanger, with recommended values for different water and glycol solutions. Glycol mixture freezing points are noted to prevent damage at low temperatures.

Installation and Operation
Guidelines include horizontal installation, air purging, maintaining proper pressure, and ensuring compatibility of solutions with exchanger materials. Specific precautions are advised to avoid damage and ensure optimal performance.

Nominal Data
Nominal data for various models include inlet and outlet water temperatures, evaporation and condensation temperatures, fouling factors, superheating values, dimensions, weight, total capacity, flow rate, and pressure drop.

Specifications
Detailed specifications for various models of water accumulators and exchangers are provided, including dimensions, volume, and weight. Models such as TWA 660, TWA 1100, TWA 1250, TWA 1500, and TWA 2000 are listed with specific measurements for supports, volume, and design parameters.

Procedures
The document outlines the use of water accumulators in modern refrigeration systems, serving as thermal flywheels for consistent operation and temperature control. The integration of THERMOKEY Shell & Tube exchangers with TWA series accumulators is discussed, highlighting benefits like compactness and ease of installation.

Standards and Recommendations
The design temperature range is specified as -10°C to +90°C with a design pressure of 6 bar. Flexible couplings and insulation are available upon request, with specific dimensions for different DN sizes.

Key Data from Tables
Tables provide detailed measurements for various models, including dimensions, volume in liters, and weight in kilograms. They also list the number of supports and design specifications for each model.

Additional Information
A schematic demonstrates the integration of water accumulators in a refrigeration system, showing connections between components like the condenser, compressor, and pump. THERMOKEY reserves the right to modify product specifications without notice.

ACCUMULATORI D’ACQUA WATER ACCUMULATORS ACCUMULATORI D’ACQUA PER SCAMBIATORI Gli accumulatori per scambiatori “TWA” vengono utilizzati nei moderni impianti frigoriferi dove sia necessaria una riserva di acqua refrigerata. Questo volano termico permette un funzionamento più continuo del gruppo frigorifero, diminuendo il numero degli arresti del compressore e assicurando nello stesso tempo una più costante temperatura del fluido freddo durante l’utilizzo. Gli scambiatori a fascio tubiero THERMOKEY possono essere inseriti, compatibilmente con la lunghezza, negli accumulatori serie “TWA” (vedere...
