PACKAGE SOLUTIONS FOR THE HVAC MARKET

Remember... ...Henry’s Law?

Phone 02 97482022 Email [email protected]

COMMONLY KNOWN AS HENRY’S LAW...A common assertion is that once you have bled all the air out of a system there is no need for any further separation. We know from Henrys Law that there is always a proportional relationship between the system pressure/system temperature, and the amount of dissolved gas in water.

When the system pressure/temperature changes, this gas will “bubble out” in the form of micro bubbles. Hence the presence of air in a system is always a threat.

Rising energy costs and increased emissions are a real problem.

The installation of an Optivent ensures the continual removal of air from the system so that the equipment is performing at its optimum performance all the time. If the release of air in the form of micro bubbles can happen anytime, then a deaerator should be a permanent fixture in the system like any other major piece of equipment.

These separators are manufactured to suit standard 1.5m/s velocity or high 3m/s velocity (greater height than the standard equivalent). Then, you can either get sealed version or demountable, where you can unbolt the bottom andpull out the internals.

The Optivent saves dollars and makes sense.Environmentally and Economically.

WHERE YOU NEED• Any open or closed loop system, from:• Chilled Water• Condenser Water• Heating Water• Process Water• Cogeneration

“In chemistry, Henry's law is one of the gas laws, formulated by William Henry in 1803. It states that: At a constant temperature, the amount of a given gas dissolved in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid.Or solubility of a gas in a liquid at a particular temperature is proportional to the pressure of that gas above the liquid.”

I don’t have air or dirt... ...in the system...do I?

Optivent

ECONOMICALLY AND ENVIRONMENTALLY - it makes cents and makes sense

WHEN YOU NEED• A must in every new installation and existing buildings. Adamant your system is very clean and no need for an Optivent? Consider again what is happening in side your system that you don't know about!• Contact Masterflow engineering team for further assistance. For existing installations, you can book in for a free site inspection.• New installations - provide necessary information and schematics for correct sizing of units.

WHO WILL WIN• The owner because he has an efficient, cost effective system and extends the life of his overall equipment.• The consultant because he has exceeded the clients expectations.• The contractor wins because he saves time commissioning the system as he no longer has the headaches associated with bleeding the air from the system. He also may reduce the losses from flushing where applicable.• The environment.

ECONOMICALLY• Energy savings-by continually removing dissolved gases, your primary equipment will achieve the same result with less power consumption.• Maintenance Free-once installed there is no ongoing maintenance such as cleaning filter elements -reduced labour costs.• Time Saving Initially-removal of air greatly aids the commissioning of the system initially saving labour costs. • Reduced Maintenance-longer time intervals between pump and valve overhaul means that over the life of the system substantial savings are achieved from less call outs, less pump & valve replacements. • Longer pipework life resulting in less capital expenditure-in bigger systems the replacement of the pipework is a far bigger concern compared to replacement of pumps or valves. Why not remove the cause of the corrosion from Day 1 and save the expensive outlay not to mention the inconvenience. Or in the case of a retrofit defer the outlay indefinitely.• Return on investment. Greater efficiency means the savings pay for itself over time.

ENVIRONMENTALLY• Less energy equals less emissions.• Reduced Carbon Content.• Less chemicals in your water treatment system-by the removal of air and dirt the chemicals will be more efficient, meaning less wastage of chemicals.• Green Star Rating - by the installation of a Optivent a green star rating may applicable.• Saves the planet.• Improved heat transfer equals lower chiller running costs resulting in substantially reduced emissions to the atmosphere over the life of the plant.• In Green Star installations the enormous loss of water when flushing may be avoided.

Not only specify an Optivent...but INSIST on it.

Air Release ValvesWhen selecting and specifying an Optivent separator always insist on the installation of an Optivent Air Release Valve.These are designed for the removal of free air that gets trapped in the highest points or dead ends in a system. The Optivent Air Release Valve is a unique leak free type. Refer to our separate brochure for full details.

AUTOMATIC PURGE OPTIONSAutomatic Purge Options add the final aspect to a maintenance free system thus eliminating manual bleeding of the Spirovent. The difference between the two different options is that the Economy version has a minor loss of pressure in the total system.
