Limited Warranty | SJ Freeze Dryer

Effective and last updated: 12 August 2026

These policies apply to products purchased directly from shop.sjialab.com from SJ Scientific Limited. They provide contractual information or benefits in addition to any mandatory customer rights. Nothing in them excludes, restricts, or replaces a right or remedy that cannot lawfully be excluded. Where mandatory law conflicts with these policies, that law prevails.

Warranty provider and statutory rights

SJ Scientific Limited, Hong Kong, provides this commercial limited warranty for SJIALAB freeze dryers purchased through this store. It is in addition to customer rights that cannot lawfully be excluded.

Year 1 — machine and supplied vacuum pump

For 12 months from documented delivery to the original purchaser, the freeze dryer and vacuum pump supplied with it are covered against defects in materials and workmanship under normal, instructed use. After diagnosis, the remedy may include operating guidance, a covered replacement part, repair instruction, repair, replacement equipment, return authorization, price reduction, or refund as appropriate.

Years 2 and 3 — sealed refrigeration system parts

For the following 24 months, coverage is limited to confirmed defects in sealed refrigeration-system parts. Covered parts may include the compressor, condenser, evaporator, and sealed refrigeration tubing as determined by our diagnosis. Refrigerant, routine charging, local labor, travel, removal, installation, and transportation are excluded unless mandatory law or our written authorization provides otherwise.

Claim and remote diagnosis

Email the order number, model, serial number, delivery date, installation location, supply voltage and frequency, site conditions, fault description, error messages, and operating logs. We may request reasonable photographs, measurements, a continuous video, or a live guided session. If video is not reasonably available, suitable alternative evidence will be accepted. Never perform an unsafe diagnostic step.

We may require a suspected failed part to be returned under RMA. An advance replacement that is not returned as agreed, or that is found operational or damaged by an excluded cause, may be charged to the customer where permitted by law.

International freight and local labor

During the applicable period, covered replacement parts and remote technical support are supplied without charge. For international service, the customer normally pays shipping, handling, export packing, return postage, insurance, customs duties, taxes, brokerage, local technician labor, travel, removal, and reinstallation. Expedited shipping and local service are chargeable unless pre-authorized.

For confirmed transit damage or an early dead-on-arrival problem, we will pay or arrange the necessary freight identified in our written RMA instructions. The customer must preserve packaging and reasonably assist with the carrier claim. Where mandatory consumer law requires the seller to bear necessary collection, postage, repair, replacement, material, or labor costs for non-conforming goods, that law prevails.

Exclusions

The commercial warranty excludes normal wear, routine pump oil, filters, maintenance seals and gaskets, consumables, cosmetic damage that does not affect operation, food or product loss, lost profit, and damage caused by incorrect voltage, phase, frequency, wiring or grounding; unstable power; improper installation or ventilation; unsuitable environment; failure to clean or maintain; accident, misuse, overloading, contamination, corrosion, unsafe materials, fire, flood, transport after delivery, or force majeure; or alteration of the serial number.

Third-party parts, service, or opening a cover do not automatically cancel all warranty coverage. Only damage actually caused by unsafe, improper, incompatible, or unauthorized work is excluded, subject to applicable law.

Replacement-part coverage

A replacement part may be new or a functionally equivalent service part. It is covered for the remainder of the original warranty or 90 days after delivery, whichever is longer.
