A completely new concept for cleaning marine fouling or other biofouling from heat exchangers. Works extremely rapidly at ambient temperature. Completely eliminates  dismantling and gasket renewal of plate-type exchangers. No environmental hazards whatsoever. The result is an oxidised and soluble ex-fouling and oxygen+water.

Plate-type heat exchangers, sea water filters and piping. Disinfecting tanks, wells and cooling water system components. Can be used to disinfect contaminated potable water systems. Can be used to remove smells from drains or toilet systems. Can be used to disinfect foodstuff areas. Usage concentration for general disinfecting cleaning: 20-10 parts clean water + 1 part Perapid. Contact times up to 1 hour at ambient temperature.

The equipment to be cleaned ( typically plate-type heat exchangers) to be isolated from the other system parts using valves, so that the reaction gases have free access up- and outward from the exchanger. Direct dosing is done through a dosing connection with valve. After the Perapid has been completely dosed this valve has to be closed to prevent gases escaping backward to the pump.

The dosing connection to be minimum 1/2" and with a stainless or plastic valve. The Perapid mix of 15-25% to be dosed into empty exchanger.

Connect the dosing hose from the dosing pump.

Use clean fresh water to make up the cleaning solution. If you cannot make all the required solution at one time, dose simultaneously the extra water needed and Perapid ES for filling up the exchanger volume. Dose the extra in as quickly as the pump makes space for dosing tank.

When all Perapid/water is pumped in, close the valve at the pump discharge or at the dosing connection and let the solution react between 20 minutes to 1 hour.

Within 60 minutes the reaction is completely depleted and can be replaced by flushing for 5 minutes with sea water or main cooling water pump. The spent solution can be boosted once by pumping in quickly some 50 l. 5% BWT GP solution followed by the main rinse after another 30 minutes reaction time.

Before attempting to use this product read carefully through all that has been written or presented as a flow arrangement. It is necessary because this product will otherwise take you by surprise. It works like no other product you have seen or experienced before.

Storage:

Store in a chemical store, separate from solvents, strong alkalies and combustable materials. Keep out of reach of children.

Goggles or face mask, synthetic wear or rain wear, boots, rubber or synthetic gloves.

The product is irritating, very close to corrosive, to skin, eyes and mucous membranes in undiluted form only. As soon as the product has been diluted with water the immediate irritating/corrosive property dissappears.

A 10% Perapid solution in Water contains about 2% active Hydrogen Peroxide. For reference,  normal mouth washes contain 3% active Hydrogen Peroxide.

The product will react with all microbiological growth and bacteria.

Perapid ES contains Hydrogen Peroxide 10-20%, Peroxide resistant wetting agent and Stabilizer.
