Details
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 |
