Do you know what's included in a reverse osmosis equipment manufacturer's "package deal"? Many customers are unclear about this, and sometimes ten manufacturers will give you ten different explanations. Some consider delivering the equipment as part of the package deal, some include installation and commissioning but ignore after-sales service, and some are simply using it as a gimmick with all the extra charges later. We at DIEN have been in the water treatment industry for over 10 years and have seen many customers misled by various gimmicks. Today, we'll explain in detail what services are included in a manufacturer's "package deal." Let's take a look!
Reverse Osmosis Equipment
The Complete Equipment Itself
A "package deal" definitely includes the equipment. The reverse osmosis unit, pretreatment system, high-pressure pump, membrane modules, control cabinet, piping and valves—all of these must be clearly stated in the contract. Some manufacturers offer low prices, but the membranes are from unknown brands, and the pumps are leftover stock. You might not see it at the time, but you'll know after six months of use.
Let me tell you, last year a client in Xi'an hired a small manufacturer for a turnkey project. The contract was vague, and when the equipment arrived, the membrane was refurbished, the pump was making strange noises, and the control cabinet wiring was a mess. In the end, the repairs alone cost 12.000 yuan, more than double the money they initially saved. I've seen this kind of thing far too many times.
Installation and Commissioning
When the equipment arrives on-site, does installation and commissioning count as a turnkey project? Theoretically, yes, but some manufacturers will come and tell you, "This will cost extra," or "That's not included." To put it bluntly, this is a common tactic: winning the bid with a low price and then adding extra items later. Reputable and capable manufacturers will include the on-site installation and commissioning services in the contract, detailing the installation and commissioning process, water quality testing, and other delivery details, ensuring everything is in order before considering delivery complete.
Reverse Osmosis Equipment
There are some uncertainties, such as the raw water quality at the site differing from the initial testing, requiring adjustments to the plan. These can be negotiated, but you can't just raise prices on the spot. If you have any concerns about the price of reverse osmosis equipment (click to view DIEN Water Treatment's price range), we suggest you consult several companies for comparison. However, we want to remind you not to focus solely on the lowest price. You get what you pay for. Extremely low-priced equipment will inevitably have poor configurations. For example, the core component, the reverse osmosis membrane, might be a low-quality, unknown brand. Make sure you understand this clearly. Also, make sure the manufacturer provides after-sales service. After all, the equipment isn't a one-time purchase; the reverse osmosis membrane will need to be replaced every 3-5 years. All after-sales service must be clearly understood to avoid being unable to find support later.
We're not buying reverse osmosis equipment and then discarding it after a year. Therefore, after-sales terms must be written into the contract, including response time, spare parts supply, and regular inspections. DIEN Water Treatment provides free on-site service during the warranty period and long-term supply of consumables. We don't play the trick of disappearing after you pay.
After working in this industry for a while, you'll understand that the difference in the equipment itself isn't that significant. What truly differentiates us is whether the manufacturer is willing to take responsibility for your after-sales service. Do you have price quotes from the manufacturers you're comparing? Send them to me and I'll check if there are any hidden pitfalls.
