Want to know more about WYIN Regulators?


Why is a twin stage regulator better than a single stage?

WYIN Compact Regulators are the first on the market in this size to have 'Twin Stage' functionality. So what does 'twin stage' mean and how does it work you ask? Well CO2 in a filled cylinder has a pressure anywhere between 700-1000psi within normal operating temperatures. The regulators job is reduce this pressure down to an operating pressure suitable for aquarium CO2 injection (30-50psi). Then using the fine-tuning needle valve the flow rate can be adjusted to a 'drop per/second' rate which is determined using the attached tubular bubble counter filled with water. Often the rate is only a few drops a second but the exact amount depends on the size and demand of your aquarium plants. You might have heard that a twin stage regulator holds pressure when faced with resistance in the line. This is correct and what this means is that the regulator will maintain it's preset 30-50psi pressure with resistance in the hose rather than drop it's pressure and stop gas flow. So why does this pressure resistance occur and how will you know if a twin gate regulator is for you? Pressure resistance is created from the atomizing or diffusing device designed to finely bubble the CO2 gas into your aquarium. If you plan on using an atomizing or diffusing device that requires high pressure to push gas through it then this feature is absolutely necessary. These are predominantly atomizers that are designed to be installed on your filters outlet hose and are called 'inline atomizers'. Normal ceramic disc style diffusers such as the regular glass diffusers do not require much pressure and are suitable for both single and twin gate regulators. If are planning to use an alloy splitter to split your CO2 injection system to feed other aquariums this will increase the CO2 demand and overall pressure resistance in the lines also. In this case a twin stage regulator that can hold a solid base pressure is also required.   


There are many really impressive features of the WYIN regulators. 

Besides its internal twin gate configuration as explained above, there are some fantastic and unique design features that really impress us about this new WYIN 'Professional' model regulator. The base pressure adjustability feature is a brilliant function to have if you want to either decrease the base pressure to give an even finer needle valve adjustment or increase the base pressure to ensure consistent fine flowing bubbles through the most stubborn of atomizers or if splitting the system amongst numerous aquariums. There is no limit to how many tanks you can run with this model, it's amazingly versatile and equally powerful. Internally this regulator cannot be faulted it's just so well designed. From it's machining to it's industrial grade seals to it's completely unique unbreakable O-ring between the regulator and cylinder, it's really got all bases covered. Externally you can see it looks beautiful and is exceptionally well designed with a clean anodized finish. All of the units sold from Aquascape Design will be supplied in stealth black despite the entire WYIN range being available in many different colors.


WYIN Electronic solenoid valves.

All WYIN Regulators come fitted with a extremely high quality electronic solenoid valve. Electronic solenoid valves provide a user friendly functionality to your CO2 Injection experience by powering on and off your CO2 between light and dark hours respectively. Anyone that has had experience with CO2 injection solenoids would know that it's hard to find a reliable one. Why is that? Australia has what is commonly known as a 'dirty' supply of power. Electricity is delivered to our households with fluctuating frequencies which puts unnecessary load on appliances. Unfortunately that load is detrimental to the longevity of most solenoids. Australia also experiences numerous spikes small and large with the smaller ones often going unnoticed unless of course you have CO2 Injection on your Aquarium. Most brands of CO2 Regulators are not immune to solenoid issues and key to consumer is to do your research and avoid those regulators. Solenoid reliability is an area that I really wanted to address because we believe you should expect years of service from a solenoid not months... 

Just like our CO2PRO range of regulators the WYIN regulators solenoid is a brilliant design based on the tried and tested Nass Magnet solenoids with circuitry designed specifically to withstand Australia's power supply issues. In the unlikely event your premises are hit with a power surge big enough to blow a PC power supply, don't worry we have extremely well priced replacement solenoids ready to ship. 

The WYIN blog...

We first met up with the WYIN team in November 2015 at a trade show in Shanghai China and we were instantly impressed with the quality and workmanship of the entire range. Their marketing was great, their packaging was fantastic and their product quality and inclusions were great. For example, they have a plastic wrapped wrench for attaching the regulator, which I really loved because I don’t like scratches. We arranged samples of their full range and we have been testing them thoroughly ever since without a single issue. We believe that the WYIN CO2 regulator range is of a higher standard than any other units we've tested, including our own brand CO2PRO (commissioned through DICI Machinery). WYIN's business strategy is good. They are looking to penetrate the international market aggressively and have the product, the marketing strategy and the pricing to do so. WYIN are set to become the market leaders in CO2 regulators and related equipment worldwide and we're very happy to be making a contribution to that.
