  • Page 8: Section One - General Description, Installation, Operation

    SECTION ONE - GENERAL DESCRIPTION, INSTALLATION, OPERATION 1.0 Nomenclature The TCR-109 is specifically designed to fit the bottom side rail of beam and frame tanks. The last two digits record the “as built” details. As ISO convention dictates, we label the rear of the tank container as the end with the discharge valves.
  • Page 9: Circulating Pump Assembly

    allows the compressor to produce lower temperatures for the cargo without adding additional weight. 1.3 Circulating Pump Assembly The circulating pump assembly is a close-coupled centrifugal pump and motor. The circulating pump assembly is low maintenance with sealed bearings supporting the motor and the fluid being pumped through it provides lubrication for the pump.
  • Page 10: Connecting Tcr-109 To The Tank Cooling System

    The unit has two holes fitted with M10 X 1.5 nut inserts, on each end, adjacent to the bottom rail cutout. These are to be used in conjunction with a simple angle to attach the unit to the beam. The rear of the unit can have additional threaded holes. The rear of the unit requires some support to resist the turning moment, as the unit will want to rotate about the bottom rail.
  • Page 11: The Expansion Tank System

    This is equivalent to the expansion tank found next to the radiator in most modern cars. Klinge Corporation can supply a bolt-on tank or the builder can fabricate it as part of the tank frame. It is basically very simple, and we suggest the builder fabricate and install it rather than have to integrate a U.S.
  • Page 12: Installation Checkout Procedure

    On initial filling, air tends to be trapped in this area and should be vented. Klinge Corporation can supply the vents, but we need to look to the installer to provide the pipes through the insulation. Without final details of the heating coils it is impractical to suggest how many vents are required.

Check that the door gaskets seal properly. 1.9.2 Starting the TCR-109 Connect the main power plug into a receptacle rated at 480V AC to supply power to the unit.

  • Page 17: Section Two - Detailed Functional Description

    SECTION TWO - DETAILED FUNCTIONAL DESCRIPTION 2.1 Refrigeration System Operation The TCR-l09 refrigeration system is uncomplicated, easy to operate, and requires very little maintenance. Central in the TCR-109 is the scroll compressor, which represents the next generation in refrigeration technology and has several advantages over more conventional compressor styles.
  • Page 18: Heat Transfer Fluid) Circulating System Operation

    2.1.1 Liquid Injection System The low temperature operation of the TCR-109, down to -40°C (-40°F), requires that a liquid injection system be used to aid in controlling the compressor temperature. The advantage of this system is that it tends to be self-regulating. As pressure increases in the scroll, the demand for liquid injection increases.
  • Page 19 The DTC valve monitors the flow of liquid refrigerant into the injection port, based on the temperature of the thermal element located in the top cap thermal well of the compressor. The scroll compressor is also equipped with an internal pressure relief (IPR) valve, which opens when the differential pressure from suction to outlet reaches an unacceptable limit.
  • Page 20: Section Three - General Maintenance Requirements

    SECTION THREE - GENERAL MAINTENANCE REQUIREMENTS 3.1 Pre-Trip Maintenance Pre-trip maintenance is necessary for the operator to feel confident that the TCR-109 refrigeration system will perform adequate cargo handling. Pre-trip maintenance is simple to perform, and if conscientiously applied, will enhance the reliability of the unit. Routine pre-trip maintenance will also add to the service life of the unit.
  • Page 21: Checking And Adding Refrigerant Charge

    Always secure or close the refrigerant tank valve after use. Install all caps and covers and do not allow the cylinder to be dropped or hit by objects. To prevent explosive damage to the tank neck and valve, be certain that the tank protective cap is on when moving. Other than proper heating tools for refrigerant bottles, do not allow the refrigerant to come in contact with a flame-heated surface, flare, cigarette or any sort of heated object.
  • Page 22: Checking And Adding Refrigerant Oil

    The TCR-109 uses R-404A or R-452A refrigerant, only polyol ether can be provided to the scroll compressor. The only recommended lubricants are Klinge part number K11-00416-00, Copeland Ultra 22 CC, Mobil EAL Arctic 22 CC, or ICI EMKARATE RL 32CF. Use of any lubricant not recommended will render the warranty void.

    small leaks and are also capable of determining system tightness. This type of leak detector is recommended when troubleshooting the system for refrigerant leaks. 3.6 Evacuating the Refrigeration System Do not use the scroll compressor as a vacuum pump to evacuate the system. It is not designed to operate in a high vacuum and excessive wear of the scroll will occur.
  • Page 24: Hi-Pot Testing

    There are two types of heat transfer fluid systems. The closed pressurized system- See Section 5 for specific instructions. The open system- With the vents open or even temporarily removed, additional liquid may be added directly to the expansion tank. Once the liquid can be seen in the plastic sight-glass the pump may be operated intermittently.

The alarm LED indicators are reset by turning the control system power OFF or by the temperature reaching the set point.

    4. Undertake a function test. The controller cannot be repaired or reprogrammed in the field but a core replacement price is offered for a unit returned that can be repaired. Contact Klinge Corporation for a replacement. 4.3 Refrigeration System The refrigeration system is relatively simple. Elements have been incorporated into the design that reduce maintenance and increase reliability.
  • Page 29 The electrical control system for the TCR-109 is rugged and compact. The technician is expected to have some knowledge of electrical applications related to refrigeration systems. An understanding of electrical drawings and schematics is also helpful. Refer to table below for the fault logic decisions for troubleshooting a malfunction.

    Venting at this location should be done at each pre-trip inspection. Depending on the tank’s cooling system there may be additional vent points at the upper runs of the cooling system. Klinge suggests that they are fitted to the tank’s pipe work but are not always notified of the details.
  • Page 38 However, it may be run intermittently in the initial filling stage to assist in venting the system. Because each system is different, the volume of the cooling system is not known to Klinge Corporation, however, generally the volume of heat transfer fluid for these units, when fitted on a 20,000 liter ISO tank, would be 30 ~ 40 or more US gallons.

    Importance of removing air. Air can not get into the system in normal operations, but in abnormal conditions air may be sucked in on the low pressure side or be generated by cavitation in the pump. Air should be removed as it will promote corrosion and could get trapped and create an airlock blocking the flow of heat transfer fluid.
  • Page 41 Take care not to add air into the system; the valve can be slightly opened to fill the hose with heat transfer fluid before making the connection. If all the air has not been removed from the system it will compress and prevent the addition of heat transfer fluid. Heat transfer fluid could also be added at any of the vent valves.

    Caution: This unit uses R-404A or R-452A refrigerant. Therefore, mineral oil type lubricant cannot be used. The only oil approved by the manufacturer is Polyol ester lubricant, Klinge Part Number K11- 00416-00, Copeland Ultra 22 cc, Mobile EAL Arctic 22cc, or ICI EMKARATE RL 32 CF.
  • Page 45 6.1.5 System Cleaning Procedure After Hermetic Motor Burnout A hermetic motor burnout failure can be detected by observing an obvious electrical fault or by a strong burnt odor to the refrigeration gas released at the discharge valve port. After a motor burnout, the following procedure must be followed to clean the system and thus prevent failure of a replacement compressor.
