Thermolar® Tank Temperature Maintenance System Installation & Operation Manual for Systems Employing THS-106 or THS-206 Electronic Controller. Precise, efficient temperature maintenance for all types of metal and plastic tanks.
INTRODUCTION INTRODUCTION The Calorique Thermolar® Tank Temperature Maintenance System is a low heat-density warming system designed to safely and efficiently maintain the contents temperature of any tank. Ideal for process control, adhesive storage (etc.) the THERMOLAR system provides uniform heat that won’t scorch tank contents. Note The Thermolar System is designed for temperature maintenance only and typically will not provide sufficient heat to significantly raise the temperature of tank contents.
Heating Elements Calorique Thermolar heating elements are factory assembled with an integral ground shield, adhesive backing and moisture-proof electrical connections. Width: 11 inches/280 mm Maximum Temperature: Do not expose any Thermolar heating element to temperatures in excess of 180°F/82°C. See pages 7 and 8 for maximum exposure temperatures of standard tank types. Lead Length: 8 feet/3.
2 Circuit Overcurrent Protection Fuse or circuit breaker rated for at least 120% of the system amperage rating. Fault Protection The power supply must include a fault detector suitable for equipment protection. This may be integral with the overcurrent protection. INSTALLATION Note For best results, insulate underneath the tank. If the underside will not be accessible after installation of the Thermolar system, then install insulation prior to final placement of the tank.
HEATING ELEMENTS 3 Note Do not install heating elements when the air and/or tank temperature is below 35°F/2°C. Below this temperature the adhesive backing initially may not stick properly. Once the heating elements have been secured in place for at least 24 hours, temperatures at or below 35°F/2°C will not adversely affect the adhesive. Attach heating elements to the tank sidewall using the adhesive backing provided.
4 THERMO-SENSORS 1. Using duct tape, attach the Over Limit thermo-sensor (marked with red) to the central area of the upper-most heating element. Locate the sensor approximately 1-1/2 ft/450 mm from the cord end of the heating element. 2. Using duct tape, attach the Maintenance thermo-sensor directly to the tank wall approximately 6 inches/150 mm from the bottom-most heating element.
5 ELECTRICAL CONNECTIONS 1. Measure and record the resistance of each heating element. Record the measured resistances on the label on the back of the control unit face plate. 2. Route all wiring to the control unit as shown in the following figure. Metal tanks must be properly grounded before operating the system. Do not run power cords or thermosensor wires over heating elements.
6 Over Limit Sensor Input Power Maintenance Sensor INSULATION Insulate the tank using the type and thickness insulation indicated on the System Component List. This insulation factor has been used to calculate the heating load required by the system: using less insulation may result in contents damage. Note Make sure that the control unit cover is securely in place before insulation is applied to the tank to ensure that no insulation gets into the control unit itself.
7 The over-limit and low-limit temperatures are used in conjunction with the on-board indicator lights and/or remote alarms to indicate a fault situation. If the over-limit temperature is reached, power to all elements will be shut off. Note The control unit will normally be preprogrammed with the temperatures specified when the system was ordered. Before operating the system, confirm the temperature programming.
8 MAXIMUM OPERATING TEMPERATURES (continued) Linear Polyethylene Tanks Maintenance Temperature: Over Limit Temperature: Low Limit Temperature: up to 120°F/50°C up to 130°F/55°C up to 115°F/45°C OPERATION Under normal operating conditions, no adjustment is necessary. It is suggested that the liquid level within the tank be maintained to at least the level of the highest heating element. This will ensure that each heating element is operating at its peak efficiency.
