HEAT EXCHANGERS

Product catalog summary
Overview
This document provides comprehensive technical information on the heat exchangers offered by OMT Group, detailing their design, specifications, and applications. It covers various series of heat exchangers, technical specifications, installation, maintenance, and ordering information.
Company Profile
OMT Group is a modern enterprise with over 55 years of experience in hydraulics, committed to innovation and quality, adhering to ISO 9001:2015 standards, and embracing Industry 4.0.
Product Range
The document outlines several series of heat exchangers, including the SS, SS2, and SD Series, each designed for specific applications and flow rates, with detailed technical data provided.
Technical Specifications
Heat exchangers are made from high-quality materials like aluminum, ensuring high thermal conductivity and pressure resistance. Key specifications include a nominal pressure of 25 bar, test pressure of 35 bar, max temperature of 120°C, and compatibility with mineral oils and water-oil emulsions.
Installation and Maintenance
Recommendations include using a by-pass valve for protection during startup and ensuring unobstructed air flow. Maintenance involves cleaning both the oil and air sides using compatible detergents and compressed air.
Ordering Information
The document provides guidance on ordering the appropriate heat exchanger, including options for different motor types and thermostat settings. Special applications require consultation with OMT's commercial department.
Conclusion
OMT Group offers a comprehensive range of heat exchangers designed to meet various industrial needs, backed by a strong commitment to quality and innovation.
Technical Features
Each model includes performance and pressure drop diagrams for 32 cst oil viscosity, with correction factors for specific operational conditions. All models are equipped with a thermostat and flow separator for efficient operation.
Recommendations
Ensure the oil flow rate is within the suggested range for optimal performance. Regular maintenance of the fan and thermostat is recommended to maintain efficiency.
Electronic Thermostats
The document describes electronic thermostats designed for controlling DC loads, featuring integrated soft starter control, speed regulation, and reverse rotation programming. Key specifications include a supply voltage of 12-24VDC, maximum load of 20A, and IP67 protection.
Installation and Maintenance of Heat Exchangers
Heat exchangers should be installed without air flow obstructions, with specific distances maintained from the fan. Maintenance involves cleaning with warm water or steam, ensuring the electric motor is disconnected and protected during the process.
Performance and Calculations
The specific dissipation heat is calculated using the formula: η = Q / (oil T° - air T°), where Q is the thermic power in kcal/h. Thermic power can be empirically calculated as Q = 0.40 V Δto, where V is the oil flow in lt/h and Δto is the temperature difference between oil in and out.
Special Applications
For applications not covered in the catalog, contact OMT's commercial department for feasibility studies.
SA Series Heat Exchangers
The SA series of water-oil heat exchangers are designed for high thermal efficiency up to 75 kW, with inspectable water circuits and options for industrial and marine environments. They feature a tube bundle design for optimal thermal yield and water savings.
Installation Guidelines
It is crucial to leave adequate space for the heat exchanger during installation to allow for easy access and maintenance. Safety valves should be installed to isolate the exchanger without fluid loss.
Certification Information
The document includes a management system certificate for OMT Group S.p.A., confirming conformity to ISO 9001:2015 for the design and manufacture of heat exchangers and related components.
