Overview

This document provides detailed technical specifications and descriptions of thermoregulation units designed for controlling the temperature of various fluids including oil, water, and pressurized water. The units are equipped with pumps, heaters, cooling systems, and control electronics to maintain precise temperature regulation for industrial processes.

1. Oil Thermoregulating Units (Range +40°C to +200°C)

Specifications and Components

• Pump: Peripheral centrifugal motor pump with special mechanical seal suitable for oil at up to 200°C.
• Heaters: Low specific power stainless steel electric heaters without gaskets.
• Cooling: Indirect cooling via stainless steel AISI 316L brazed plate heat exchanger using wasted water, equipped with an electro-valve for flow control.
• Expansion Tank: Open expansion vessel to accommodate oil volume increase due to temperature rise.
• Safety Features: Electric float for oil level control that shuts off heating resistance if oil is absent; automatic air vent during filling; pressure gauge for monitoring thermoregulated fluid pressure.

Models and Performance Parameters

The document lists multiple models (e.g., TO-200-43, TO-200-46, TO-200-86) with varying heating power (3 to 12 kW), pump delivery rates (20 to 140 lt/min), and pressure ratings (up to 15 bar). Cooling fluid is typically water at different flow rates (15, 45, 90 lt/min).

2. Fluids Temperature Control Units

General Features

• Microprocessor-based digital electronic regulator with PID control for precise temperature, timing, and alarm management.
• Controls both heating and cooling sections with digital display of operational status and faults.
• RS 485 serial interface supporting Modbus protocol for communication and remote control.
• Includes main power switch, pump protection, and leak stopper system enabling operation under pressure or vacuum for system draining.

Cooling and Heating Circuit

• Water recycle pump with immersed body, no mechanical seal, suitable for operation up to 160°C.
• Stainless steel low power heaters immersed in tank.
• Indirect cooling via tubular heat exchanger immersed in tank, with electro-valve for water flow control.
• Stainless steel atmospheric pressure accumulation tank with electric float level control and automatic refill valve.
• Mechanical filter and pressure gauge included.

3. Water Temperature Control Units (Leak Stopper Range +30°C to +90°C)

Design and Features

• Leak stopper system manually activated to allow operation under vacuum for draining purposes.
• Thermoregulated water recycle pump without mechanical seal, suitable for water up to 160°C.
• Low specific power stainless steel heaters, sealed and immersed.
• Indirect cooling with wasted water, electro-valve controlled, and inspectable filter.
• Stainless steel expansion and accumulation tank with automatic filling and pressure gauge.

Models and Parameters

Models such as TA-98-43, TA-98-49, TA-98-418 are specified with heating power from 3 to 18 kW, pump flow rates from 10 to 50 lt/min, and pressure ratings up to 15 bar.

4. Pressurized Water Thermoregulating Units (Range +40°C to +150°C)

Key Components

• Centrifugal motor pump with special mechanical seal for water up to 150°C.
• Low specific power stainless steel heaters with sealed construction, no gaskets.
• Indirect cooling via stainless steel AISI 316L brazed plate heat exchanger with electro-valve.
• Closed expansion tank with nitrogen pre-charge for pressure stabilization.
• Pressure gauge for fluid monitoring.

Models and Performance

Models such as TA-150-43, TA-150-49, TA-150-818, and TA-150-836 offer heating power from 3 to 36 kW, pump delivery rates from 10 to 180 lt/min, and pressure ratings up to 15 bar. Cooling fluid is water at various flow rates (15, 45, 90, 135 lt/min).

Critical Parameters and Best Practices

• Ensure correct pump and heater selection based on maximum design temperature and required heating power.
• Use indirect cooling with appropriate flow rates of cooling water to maintain system efficiency.
• Monitor fluid pressure and level continuously using provided gauges and electric floats to prevent damage.
• Utilize the leak stopper system when draining or operating under vacuum conditions to avoid fluid loss and maintain system integrity.
• Regularly inspect filters and electro-valves to ensure proper operation and prevent clogging.
• Employ the microprocessor-based PID controller with RS485 Modbus interface for precise temperature control and integration into process control systems.
