HEB series

Product catalog summary

Overview: The document provides technical data and specifications for the Series HEB Thermoelectric Bath, a Peltier-type device used for precise temperature control of liquids. It highlights the environmentally friendly features, operational benefits, and application areas of the product.

Specifications: The Series HEB Thermoelectric Bath offers temperature stability of ±0.018°F and distribution of ±0.036°F. It is heaterless, refrigerant-free, and features a dual tank construction for consistent temperature. The device is compact, with reduced vibration and noise compared to refrigerated types.

Key Features: The bath uses a Peltier element for heating and cooling, allowing rapid temperature shifts. It includes a circulating pump and temperature sensor for accurate fluid temperature display. The device is suitable for various chemical processes, semiconductor tests, and materials with high viscosity.

Applications: The bath is used in chemical processes like MOCVD, diffusion gas temperature control, and thermal testing. It supports chemicals and liquids with high viscosity and is applicable in physical and chemical analysis.

Technical Details: The bath operates with a cooling capacity of 140 W and a heating capacity of 300 W. It supports a temperature range of 5.0 to 140.0 °F and uses clear water or fluorinated liquids as circulating fluids. The device is equipped with safety features like overheating protection and fan rotation monitoring.

Maintenance and Precautions: The document advises on regular maintenance, including replacing parts like the circulating pump and fan every 3 to 10 years. It emphasizes the importance of using specified fluids and maintaining appropriate fluid levels to prevent damage.

System Design and Communication: The bath includes RS-485 and RS-232C communication options. It requires careful system design to ensure safety and compatibility with customer systems. The document also provides guidelines for facility water quality and handling precautions.

Specifications and Standards:

Water Quality Parameters: The document outlines standard values for various ions and compounds in facility water, such as Iron (Fe), Copper (Cu), Sulfide ion (S2–), and others. These parameters are crucial for preventing corrosion and scale generation.
Operating Pressure: The maximum operating pressure for facility water is 73 psi (0.5 MPa). Exceeding this pressure can cause internal piping damage and leakage.
Flow Rate: The recommended flow rate for facility water is between 0.8 to 1.3 gpm (3 to 5 L/min). Flow rates outside this range can affect cooling and heating capacity.

Procedures:

EEPROM Usage: The set value can be written to EEPROM up to approximately 100,000 times. Users should monitor the frequency of writing operations.

Maintenance and Safety Precautions:

Electric Shock and Fire Prevention: Avoid operating switches with wet hands and ensure the Thermoelectric Bath is free from water or fluid.
Error Handling: In case of errors like abnormal sounds or smoke, immediately cut off power and stop water supply. Contact SMC or a distributor for repairs.
Regular Inspections: Monthly checks should be conducted by knowledgeable operators. Inspections include checking displayed contents, temperature, vibration, power supply, fluid leakage, and air flow conditions.
