Ancillaries for Dosage

Description

Dosage Tank and Bunds

A range of Dosing Tanks and bunds manufactured from medium density polyethylene suitable for internal storage of a wide variety of chemical products, as part of an automatic dosing and control system.

Dosage tanks are available in 50, 100, 200, 500 and 1000 litre sizes.

They can be supplied in either natural (translucent) or black.

For ease of chemical addition a large filler hole with lid is provided and suitable storage of concentrated, diluted or mixed (to supplier’s instructions) products can be achieved.

All tanks are graduated to facilitate monitoring of chemical usage. Metering pumps can be mounted on the top surface of the dosage tanks with suitable fixings (not supplied).

Dosage tanks should always be located in a suitable bund to ensure that any spillage of chemical is contained within a safe area.

Standard bunds are circular in shape and available in natural (translucent). They are designed to contain the nominal   capacity of all the standard dosage tanks, i.e. 50, 100, 200, 500 and 1000 litre sizes.

All the tanks are for general purpose in an internal environment, protected from freezing conditions. The choice of tank is determined by the storage volume required.

Black tanks are intended for use with oxidising chemicals such as chlorine, sodium hypochlorite, chlorine dioxide solutions or other products which suffer degradation by UV light.

Health and Safety

It is a legal duty to comply with the Control of Substances Hazardous to Health Regulations relating to the mixing and handling of chemicals.

The contents of all dosing tanks should be clearly identified and Product Safety Information Sheets and Dosage Instructions should be displayed at the point of use.

IN PARTICULAR THE HANDLING INSTRUCTIONS SHOULD ALWAYS BE OBSERVED BEFORE ATTEMPTING TO USE ANY CHEMICAL.

Water Meters

A range of hot and cold rated multi-jet water meters is available in two categories:

Non Pulsed: to measure the throughput of water and enable readings to be logged as required. A reading of the total volume is available in m3 and litres.

Pulsed: used as part of Dosage Control Systems or directly with externally paced pumps. The “K” factor of the water meter specifies the volume of water passing through the meter between pulses. These meters also give the same volumetric readings as the non-pulsed units.

 

Valves

Cooling Water Solenoid Valves

Solenoid Valves offered specifically for cooling water bleed.

A range of normally closed (powered to open) two-way valves.

Double Walled Dosage Line Tubing

In some locations or applications, chemical leakage just cannot be contemplated at any time. This could be typically when a dosage line goes through a highly sensitive process area, or through a false ceiling, over a highly populated commercial or retail area for example.

For applications such as these, double walled tubing is available so that if the inner tubing does fail, the leak is contained within the outer tubing and transported to a less sensitive area.

Manual Drum Pump

Ideal for dispensing hazardous chemicals direct from a 20 / 25 litre capacity drum. Utilising a closed loop system for full safety during dispensing. The pump dispenses approximately 180ml per stroke.
