OneFlow Series – For Hot Water
OneFlow® Anti-Scale System For Hot Water
Connection Sizes: 1″ and 2″ (25 and 50mm)
Flow Rates: 2 gpm to 75 gpm (7.6 lpm to 285 lpm)
The OneFlow® Anti-Scale System for hot water provides protection from scale formation on internal and external surfaces where the hot water feed line is being further heated (booster heater) or brought to steam (steam generator, autoclave).
The OneFlow® system uses specially designed components to work in applications where the water is heated between 100°F – 150°F (38 – 66°C) but has not yet been treated for scale control. These types of applications typically involve protecting and extending the life of equipment and instruments from the damaging effects of hard water scale. OneFlow® prevents scale by transforming dissolved hardness minerals into harmless, inactive microscopic crystal particles. These crystals stay suspended in the water and are passed to drain thereby having a greatly reduced ability to react negatively, like dissolved hardness does, particularly in high temperature applications where scale formation is accelerated. The system requires very little maintenance, no backwashing, no salt and no electricity. Typical hardness problems, especially build-up of scale in boilers and steamers are no longer a concern. OneFlow® is not a water softener. It does not add chemicals or remove any minerals. It is a scale prevention device with proven 3rd party laboratory test data and years of successful Commercial and Medical applications. OneFlow® is the one water treatment device that effectively provides scale protection and is a great alternative to other scale treatment devices.
- Chemical free scale prevention and protection – converts hardness minerals to harmless, inactive microscopic crystals
- Virtually maintenance free – No salt bags or other chemicals to constantly add or maintain
- No control valve, no electricity and no wastewater
- System and components designed to work specifically with hot water applications
- Uses environmentally friendly – “green” technology
- Simple sizing and installation – all you need to know is pipe size and flow rate
- Built-in bypass valve provides flexibility for off-line service or media replacement
- OneFlow® does not add anything to the water
- Long life media requires replacement once every three years
- Effective retro-fit technology where scale control was not previously considered.
- Improves efficiency of all hot water boosting or steam generating equipment
The wetted surface of this product contacted by consumable water contains less than one quarter of one percent (0.25%) of lead by weight.
A OneFlow® scale prevention system for hot water shall be installed on the hot water feed line just prior to the equipment it is intended to protect. The temperature of the hot water feed line should consistently range between 100°F – 150°F (or 38°C – 66°C) as all of the components are designed to work in this elevated temperature condition. The OneFlow® system shall effectively reduce water hardness scale concerns thereby protecting heat-transfer and other surfaces from the negative effects of scale. The system shall be plumbed with a bypass valve to allow isolation of tank(s) and to allow the bypass of untreated hot water in the event that service or media replacement be necessary. The installation area should be suitable in size for the tank(s) to be serviced without encumbrance and for the tank to sit upright on a flat level surface.
The system must not require backwashing, regeneration or any need to discharge water once put into service. The system must not require any chemical additives and must not require electricity for operation. The system must operate in an up-flow manner to minimise any pressure drop.
Note: Copper lines need to be passivized for a minimum of 4 weeks before placing unit into service. Not for use on closed loop systems.
