FREY AG Product Lines We Repair
Our engineers are trained on the full FREY AG product range. Below are the major product families we service.
FREY Pressure Filters (High-Pressure Series)
High-pressure inline filters for main hydraulic circuits operating at 280-350 bar. Common issues include clogged filter elements causing pressure buildup, faulty differential pressure indicators, and electronic blockage sensors triggering false alarms in CNC and injection molding equipment.
FREY Return Line Filters (Tank-Top Series)
Suction and return filters mounted on hydraulic reservoirs for secondary circuit filtration. Repair needs include damaged magnetic inserts, worn float valves, and non-responsive level switches in steel mills, textile machinery, and paper production plants.
FREY Offline Filtration Units (Mobile Conditioning)
Portable kidney-loop filter carts and offline conditioning systems used during maintenance or commissioning. Common faults include failed motor contactors, blocked suction strainers, and temperature sensor malfunctions in pharmaceutical and food processing facilities.
FREY Electronic Control Modules (ECM)
Programmable logic controls and sensor interfaces for filter blockage monitoring, pressure regulation, and alarm signaling. Issues stem from water ingress in humid Indian climates, relay failures, and corrupted firmware causing nuisance shutdowns.
FREY Bypass and Differential Pressure Valves
Pilot-operated relief and bypass valves protecting filter housings from overpressure. Failures include stuck poppet elements, seal degradation from contaminated fluid, and calibration drift causing improper opening thresholds.

Common FREY AG Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FREY AG equipment arriving at our workshop.
- ✓Differential pressure indicator stuck or non-responsive — FREY pressure gauge blockage or mechanical linkage corrosion in humid environments. Contaminated hydraulic fluid deposits accumulate inside the indicator mechanism, preventing dial movement even when filter element clogs.
- ✓Electronic blockage sensor signal loss or constant fault — FREY ECM sensor wire corrosion due to moisture ingress through cable glands in monsoon-affected Indian facilities. Salt-laden air in coastal plants accelerates connector oxidation, breaking the 4-20mA signal loop.
- ✓Bypass valve opens prematurely or fails to seal — FREY pilot relief valve poppet worn from cyclic pressure spikes or contaminated fluid particles scoring the sealing surface. Loss of pilot pressure due to blocked orifices also prevents valve closure.
- ✓Motor contactor chatter or chattering on offline filtration cart — FREY ECM 24V supply voltage fluctuation caused by loose terminals or aged capacitors. Magnetizing coil residue or pitted contact surfaces in the 3-phase starter prevent stable contactor engagement during startup.
- ✓Filter element bypass occurs prematurely (low micron rating bypass) — FREY bypass valve calibration drift or damaged differential pressure spring in high-temperature environments (>60C ambient in Indian summer). Element deformation from pressure cycling also opens unintended bypass flow.
- ✓Suction line filter blockage or cavitation noise in pump inlet — FREY suction strainer clogged with rust particles from aged hydraulic reservoirs or system flushing debris not properly removed. Undersized inlet line also causes vacuum conditions, triggering cavitation noises.

Frequently Asked Questions — FREY AG Repairs
Do you repair FREY AG equipment anywhere in India?+
Yes. Synchronics repairs the complete FREY AG product range including pressure filters, return filters, offline filtration carts, bypass valves, and electronic control modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all major cities. All repairs are handled at our 180+ engineer facility in Vadodara, Gujarat, with typical turnaround of 5-7 working days.
What is the typical cost of repairing a FREY pressure filter blockage sensor failure?+
FREY ECM sensor repairs typically cost INR 8,000-15,000 depending on connector replacement needs and calibration. If the entire sensor unit requires replacement, costs range INR 18,000-25,000. Synchronics provides upfront quotes after initial diagnostics. Many sensors are repairable by cleaning and connector restoration, offering cost savings versus replacement.
Can Synchronics repair FREY offline filtration cart motors that won't start?+
Absolutely. FREY FOK-series carts often fail due to contactor chatter, voltage supply issues, or thermal overload tripping. Synchronics diagnoses the entire starter circuit including the 24V control supply, replaces aged contactors or relay modules, and verifies motor winding resistance. We pressure-test the cart under load before delivery to ensure full functionality in your facility.
How often should FREY filter elements be replaced in Indian humidity and dust conditions?+
FREY recommends element replacement every 2,000-3,000 operating hours or when differential pressure reaches the bypass threshold (typically 3.5 bar). In Indian monsoon regions with high dust ingress, quarterly inspections are prudent. Synchronics offers condition monitoring support and can advise on element grades suited to your specific hydraulic environment and contamination exposure.
Do FREY bypass valves need recalibration after a pressure spike event?+
Yes. After a hydraulic shock or pressure transient exceeding system rating, FREY bypass and relief valves should be pressure-tested and recalibrated. Synchronics has precision test benches capable of verifying cracking pressures within 0.5 bar tolerance per DIN ISO 4401. We also inspect for poppet wear and replace springs if calibration cannot be held reliably.
How do I send my FREY AG 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 FREY AG 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 FREY AG 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 FREY AG 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.
