DELTECH Product Lines We Repair
Our engineers are trained on the full DELTECH product range. Below are the major product families we service.
Refrigerated Dryers (DT Series)
DELTECH's DT refrigerated dryers remove moisture from compressed air using cooled-surface technology. Common repairs include failed evaporator coils, thermostatic expansion valve (TXV) malfunctions, defrost cycle failures, and refrigerant charge loss. Indian plants operating 24/7 often experience separator efficiency degradation.
Desiccant Dryers (DA/DB Series)
Heatless and heated desiccant dryers for ultra-low dew point applications in pharmaceutical and electronics manufacturing. Repair focus: silica gel saturation detection, desiccant cartridge blockage, solenoid valve stiction, and tower isolation ball valve leakage common in humid Indian climates.
Process Chillers (CP/CW Series)
DELTECH CW and CP series water chillers maintain stable coolant temperatures for injection molding, die casting, and precision machining. Frequent failures: refrigeration compressor wear, condenser fouling in dust-heavy environments, water pump cavitation, and temperature sensor drift in fluctuating ambient conditions.
Air Filtration Modules (AF/FG Series)
Multi-stage coalescent and activated carbon filter cartridges integrated with DELTECH dryers. Repair and replacement of clogged filter elements, bypass valve sticking, and differential pressure indicator failures typical after 6-12 months in Indian industrial environments with high particulate load.
Control Boards and Instrumentation (DCB Series)
DELTECH digital control boards manage dryer cycles, chiller setpoints, and alarm outputs. Common repairs: humidity sensor failure (capacitive drift), contactor burn-out, relay chatter, and loss of 4-20mA output signal to PLC. Moisture detection boards particularly vulnerable to condensation ingress in coastal plants.
Expansion Valves and Solenoids (EV/SV Series)
Thermostatic expansion valves (TXV) and proportional solenoid valves control refrigerant flow in DELTECH chillers and dryers. High failure rate: valve seat erosion from refrigerant particulate, solenoid coil burnout in high-vibration machine tool installations, and seasonal ice formation during monsoon shut-downs.

Common DELTECH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DELTECH equipment arriving at our workshop.
- ✓Refrigerated dryer not achieving target dew point — DELTECH DT series dryers rely on precise thermostatic expansion valve (TXV) calibration and adequate refrigerant charge. Failure typically stems from TXV bulb loss of sensitivity, low refrigerant level from micro-leaks in copper tubing, or evaporator coil icing due to defrost thermostat malfunction common in Indian monsoon conditions.
- ✓Desiccant dryer dew point creep above specification — DELTECH DA/DB dryers fail dew point control when silica gel or molecular sieve cartridge becomes saturated—a rapid issue in Indian coastal and monsoon regions. Root causes: blocked or damaged cartridge, failed solenoid dump valve preventing purge air flow, or pressure switch malfunction causing missed regeneration cycles.
- ✓Chiller temperature unstable or overshooting setpoint — DELTECH CP/CW chillers with faulty proportional solenoid valves or malfunctioning temperature sensor modules cause oscillation or lag in coolant control. Common in Indian die-casting shops: thermistor drift from thermal cycling, solenoid response lag due to coil resistance change, or hunting cycles from PID control loop instability.
- ✓DELTECH control board humidity sensor reading erratic or maxed out — Capacitive humidity sensors in DELTECH DCB-2000/3000 boards drift with age and are susceptible to condensation ingress, salt spray corrosion in coastal plants, and thermal shock during power cycles. Indian plants with poor environmental control experience rapid sensor failure—typically false 'high moisture' alarms.
- ✓Water chiller pump cavitation noise and reduced flow — DELTECH CW series pump cavitation occurs from clogged inlet strainers, low coolant reservoir level, or impeller damage from hard-water scale buildup common in Indian tap water. Secondary cause: worn pump bearings and seal leakage reducing system pressure below pump suction threshold.
- ✓DELTECH dryer bypass valve leaking or stuck closed — Filter bypass valves in DELTECH DT and DA series open when filter differential pressure exceeds ~0.5 bar to prevent system starvation but become sticky or jam from silica gel dust, oil aerosol accumulation, or corrosion in high-humidity environments. Indian plants with infrequent filter changes experience worst failures.

Frequently Asked Questions — DELTECH Repairs
Do you repair DELTECH equipment anywhere in India?+
Yes. Synchronics Electronics repairs the full DELTECH product range—refrigerated dryers, desiccant dryers, process chillers, filtration modules, and control boards. We offer PAN India door pickup and drop-off from major cities: Mumbai, Delhi, Bangalore, Chennai, Hyderabad, Pune, Ahmedabad, and Vadodara. All repairs are handled at our state-of-the-art facility in Vadodara, Gujarat with quick turnaround (2-5 days typical).
What is typical cost to repair a DELTECH refrigerated dryer versus replacement?+
DELTECH DT series repairs average INR 12,000-35,000 depending on fault (TXV replacement ~INR 8,000-12,000; compressor rewind ~INR 18,000-25,000; full refrigerant circuit service ~INR 15,000-20,000). New dryers start at INR 80,000+. Synchronics prioritizes cost-effective repair; we replace only failed components and test thoroughly to extend equipment life by 3-5 more years.
My DELTECH desiccant dryer keeps showing high dew point alarms in monsoon season. Why?+
DELTECH DA/DB dryers are vulnerable to silica gel saturation during high humidity months (June-September in India) because regeneration cycles may not fully dry the cartridge in 24-hour intervals. Root causes: undersized dryer for your flow demand, blocked purge air line, failed solenoid dump valve, or incorrect regeneration temperature setting. Synchronics audits your compressed air system, checks all control valves, and may recommend a larger cartridge capacity or faster regeneration schedule for tropical climates.
Can Synchronics repair DELTECH chiller boards that have failed relays or burnt contactors?+
Yes. Synchronics specializes in DELTECH DCB control board repair—we replace burnt relays, failed contactors, shorted capacitors, and defective thermistor modules. We also reprogram board setpoints and fine-tune PID parameters if original calibration was lost. All work is backed by 12-month warranty. If board-level repair is uneconomical, we source reconditioned OEM DELTECH boards with full testing.
What warranty do you offer on DELTECH repairs?+
All DELTECH repairs from Synchronics come with a 12-month parts and labour warranty. Replaced components (solenoid valves, sensors, expansion valves, pump seals) are covered 100%. Labour warranty covers the specific fault repaired; normal wear-and-tear is excluded. Extended warranty up to 24 months is available at 15% of repair cost for critical production equipment.
How do I send my DELTECH unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a DELTECH drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on DELTECH repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your DELTECH unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
