UPC 1000 (Low Temperature Dehumidifier Batching Treatment): Pinakamahusay na Pilihan sa Selangor, KL, Malaysia Pure Cooling Engineering & Services Sdn. Bhd.

Deskripsyon

The UPC 1000 is a low-temperature dehumidifier designed for precise and efficient batching treatment. It excels in moisture removal while preserving material integrity, making it ideal for industries like pharmaceuticals, food processing, and chemical manufacturing. With robust construction and advanced technology, it ensures reliable performance, energy efficiency, and consistent quality in production.

“ Less Weight, Less Volume, Less Cost "
Modular drying system customized to meet the specific requirements depending on the application.
Sludge weight and volume reduction by level.
Disposal cost reduction by as much as 60%; a better classification may be obtained sometimes.
Drying at low temperatures between 30C to 60C.
High efficiency through the use of refrigerant technology for air dehumidification.
Reliable and uniform drying.
Energy and cost savings through a perfect combination of air conditioning and air routing.
Drying in a closed circuit / system with less waste air.
Internal and external dryer unit insulated panel S/Steel SUS304 and bolt & nuts fully Stainless Steel.

Standard Operation Procedure
1. Fill in fresh sludge into Dryer Bucket to 1000kgs (with condition sludge moisture < 70% , dryness 20 – 30% and with cake form)
2. Push in bucket into Dryer unit below the ducting until bucket stop (floor been mounted I-beam stopper)
3. Close / tight up supply air and return ducting (flexible canvas).
4. Turn ‘ON’ selector button to start operation entire unit (maximum operating 12hrs)

Electrical & Refrigerant Setting

Drying Time (8 – 12 Hrs per batch).
Compressor Overload 33 Amps. (actual running 27.8A)
Blower Overload 5.5 Amps. (actual running 2.8 - 3.0A)
Compressor High / Low Pressure Switch (Low=40psi High=360psi).
Total running ampere 30A – 32A.
External Fan : 0.6A x 2 unit = 1.2A

Preventive Maintenance

1. Every 2 batch to clean air intake filter with water only (do not use air pressure or water jet pump will damage the washable filter.)
2. Every month to carry out External Condenser Coil cleaning using water only (do not use water jet pump it will damage the Aluminium fins and chemical clean is advisable once a year). Close up / cover up control panel top part with plastic wrapping.
3. Every month to clean Cooling Coil or Heating Coil by water only (do not use water jet pump it will damage the aluminium fins and chemical clean is advisable once a year)
4. Every 3 month to check blower belting tension and condition (if found wear and tear immediate replace)

Trouble Shooting

Fault	Possible Causes	Solution
Compressor does not run	Power failure	Check the power supply
	Shut down by protection device	Check and determine the causes
	Drying time reach set point	Check the control setting time
Compressor frequent cut in / cut out	Over charged or insufficient refrigerant	Check the amount refrigerant
	High / Low Pressure Switch	Manual reset - Push Green Button
	Unsufficient Refrigerant Charge	Refrigerant leak at the system
Compressor Noisy	Power failure or wrong phase sequence	Check the power supply
	Refrigerant flow back	Check Expansion Device superheat and valve opening position
	Compressor internal Problem	Replace Compressor
Insufficient Heating-Supply Air	Insufficient Refrigerant	Check unit for leaks. Add refrigerant for the system
	Wrong expansion device setting	Check Expansion Device superheat and valve opening position. Replace it if necessary
	Filter Drier Choked	Replace filter drier
Suction Tube Freezer	Air flow rate choked / slow	Clean air intake filter, sludge bucket air hole block or sludge too lumpy
Discharge Pressure Too High	Refrigerant over-charged	Remove the excess refrigerant
Discharge Pressure Too High	External fan faulty / tripped	Check fan motor ohm and shorting issue. Replace it if necessary
Discharge Pressure Too Low	Insufficient Refrigerant	Check unit for leaks. Add refrigerant for the system
	Insufficient air flow to cooling coil	Clean air intake filter, sludge bucket air hole block or sludge too lumpy
	Wrong expansion device setting	Check expansion valve device superheat and opening position. Replace it if necessary
Blower Motor does not run	Power failure	Check the wiring
Blower Motor does not run	Motor malfunction	Replace the motor or repair
