SSE S&T EVAPORATORS

SSE S&T EVAPORATORS

Product catalog summary

Specifications:
The SSE Shell & Tube Evaporators are designed for applications such as water chilling, liquid cooling, and water heating. They are optimized for refrigerants R134a and R1234ze, with a cooling capacity of up to 2200 kW and support for up to 4 refrigerant circuits. The tube bundle is non-removable and directly welded to the shell.

Materials:
Construction materials comply with European and American pressure vessel codes, using carbon steel, copper, plastic, asbestos-free gaskets, and alloy steel bolts. Alternative materials are available upon request.

Accessories:
Optional accessories include welded saddles, compressor supports, flanged water connections, trace heating, UV protection insulation, electrical resistance, and special painting.

Standards and Testing:
Evaporators are available with CE and ASME certifications, undergo non-destructive examinations, and pressure and leak tests. They can be designed and tested according to major naval classification societies.

Installation and Operation:
Recommendations include horizontal installation, ensuring proper pressure at the water outlet, avoiding excessive vibrations, and using compatible water or brine solutions. Avoid operating near freezing temperatures without glycol and prevent cavitation and gas presence in the circuit.

Selection Guidelines:
The fouling factor is critical for selection, with specific values for different solutions. The designation system allows easy identification of model specifications.

Freezing Points:
A table of freezing points for ethylene and propylene glycol solutions is provided to prevent damage at low temperatures.

Additional Specifications:
Includes maximum flow rates (110 to 455 m3/h), weight (603 to 2400 kg), tube volume, and PED categories (II or III).

Reference Conditions:
Performance data reference conditions include water temperatures of 12-7°C, evaporator temperature of 3.5°C, and condenser temperature of 40°C. The fouling factor is 0.000043 m2*K/W.

Procedures and Recommendations:
Performance data is indicative; specific selections should use HTS software. Check refrigerant pressure drop for appropriate expansion valve selection.

Refrigerant Circuits:
Details dimensions for 2, 3, and 4 refrigerant circuits, including header diameters and installation measurements.

Accessories:
Flexible couplings for temperatures above -10°C and insulation available upon request. Dimensions for different DN and PN ratings are provided.

Warranty:
Onda S.p.A. offers an 18-month warranty against defects in materials and workmanship, excluding natural wear, unauthorized modifications, improper use, and non-compliance with installation specifications.

Exclusions:
The warranty does not cover non-compliance with laws enacted after order confirmation or specific local laws unless agreed upon. Clients must ensure compliance with local laws.

Contact Information:
Contact details for Onda S.p.A. and its international branches in the USA, France, Russia, Finland, and China are provided.

The SSE series models are designated by an alphanumeric string, which allows the customer to easily recognize the diameter, the number of refrigerant circuits, and the length of the tubes. For a given diameter, through our software it is possible to vary the tubes length and the number of internal baffles, in order to find the best compromise between size, performance and water pressure drop. The refrigerant side pressure drop in the distributor is indicated in the software too: this value is very important for the customer, in order to select the proper expansion valve and to put in the right...
