HTM Product Lines We Repair
Our engineers are trained on the full HTM product range. Below are the major product families we service.
HTM Accumulators (Bladder & Piston Type)
Pressurised energy storage units for shock absorption and flow compensation in hydraulic circuits. Common faults include bladder rupture, precharge loss, safety valve sticking, and corrosion of piston rods affecting system pressure regulation.
HTM Plate-Frame Coolers
Compact heat exchangers for machine tool coolant and hydraulic fluid cooling in high-temperature environments. Frequent repair needs include gasket leakage, internal fouling, thermal efficiency loss, and plate cracking under thermal stress.
HTM Immersion Heaters & Thermostats
Electric immersion heating elements and temperature control units for maintaining optimal fluid viscosity in injection moulding and die-casting operations. Repair focuses on heating element burnout, thermostat drift, and electrical connector corrosion.
HTM Temperature Control Units (Tempro Series)
Standalone chillers and process cooling systems for maintaining tight temperature tolerances in automotive machining and food processing. Issues include compressor failure, refrigerant leaks, control board malfunction, and sensor calibration drift.
HTM Pressure Relief & Safety Valves
Precision valve assemblies protecting hydraulic circuits from overpressure. Common faults include spool stiction, spring relaxation, pilot drain blockage, and seal wear affecting pressure accuracy.
HTM Filter & Breather Units
Hydraulic fluid filtration and moisture control systems preventing contamination-induced component failure. Repair includes element replacement, bypass valve sticking, moisture saturation of desiccant, and housing crack detection.

Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common HTM Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HTM equipment arriving at our workshop.
- ✓HTM accumulator bladder rupture and precharge loss — Long-term cycling stress, moisture ingress causing internal corrosion, or manufacturing defect in bladder material. Precharge nitrogen escapes through failed bladder, reducing system response and shock absorption.
- ✓HTM cooler gasket leakage and plate separation — Thermal cycling fatigue at plate edges, improper torque sequence during assembly, or aggressive coolant chemistry attacking gasket elastomer. Leaks typically manifest as slow weeping onto machine bed or sudden flow loss.
- ✓HTM immersion heater element burnout and open circuit — Fluid level drop exposing heating coil, corrosive coolant attacking nichrome sheath, or excessive electrical load from improper contactor wiring. Burned-out element prevents temperature setpoint reach, causing production slowdown.
- ✓HTM temperature control unit compressor failure and refrigerant loss — Liquid slugging from blocked suction line, worn piston rings reducing compression ratio, or capillary tube blockage from moisture freeze-up. System fails to cool, affecting part dimensional stability in automotive shops.
- ✓HTM pressure relief valve spool stiction and creep — Contamination settling on spool bore, pilot drain blockage restricting feedback flow, or corrosion of valve body from moisture-laden hydraulic fluid. Valve fails to open at setpoint or drifts, causing overpressure alarms.
- ✓HTM filter bypass valve opening and internal element collapse — Excessive fluid viscosity at low temperature, debris loading on element reducing differential pressure margin, or spring relaxation in bypass poppet. Unfiltered fluid circulates, causing pump wear and varnish accumulation.

Frequently Asked Questions — HTM Repairs
Do you repair HTM equipment anywhere in India?+
Yes. Synchronics is the authorised repair partner for HTM across India — accumulators, coolers, heaters, temperature control units, and pressure valves. We offer same-day PAN India pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all industrial hubs. All repairs completed in our Vadodara facility with German OEM technical documentation.
What is the typical turnaround time for HTM accumulator repair?+
Standard HTM accumulator repair takes 5-7 working days including bladder inspection, nitrogen pre-charge verification, pressure test stand validation, and documentation. Urgent repairs can be expedited to 48 hours for critical production breakdowns. We offer same-day diagnostics and pressure test reports to help you plan spare accumulator procurement while repair is in progress.
Can Synchronics handle HTM cooler leakage repairs without replacing the entire unit?+
Yes. Most HTM cooler leaks are gasket or plate seal failures — not structural damage. Synchronics disassembles the cooler, performs dye penetrant and eddy current inspection for micro-cracks, replaces gaskets with OEM materials, and re-torques all plates per HTM sequence. Helium leak test confirms repair quality. This approach saves 60-70% versus new cooler cost.
How do I know if my HTM accumulator precharge has been lost?+
Signs include sluggish machine response to load changes, inability to reach full system pressure, intermittent relief valve chatter, and reduced shock absorption during rapid actuator movement. Have Synchronics perform nitrogen pre-charge check with certified gauges — normal precharge is typically 0.6-0.8x minimum circuit pressure. We can diagnose remotely if you provide system pressure readings and machine cycle observations.
Does Synchronics stock HTM spare parts and accessories?+
Yes. Synchronics maintains stock of common HTM repair items — bladder kits, gasket sets, filter elements, immersion heating elements, thermostat cartridges, and spool valve components. We import genuine HTM spares and stock them locally to reduce repair lead times. For obsolete HTM models, we source through European distributors within 10-14 days.
How do I send my HTM 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 HTM 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 HTM 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 HTM 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.
