Safety Notice

Safety First It is important that you thoroughly read and understand this manual before operating or servicing this Peak Scientific Instruments Gas Generator. PLEASE NOTE THE FOLLOWING CAUTIONS AND WARNINGS FOR YOUR OWN SAFETY. ! Caution – Only authorized persons should operate or service this equipment. ! Warning – To avoid risk of electrical shock, personal injury, or death disconnect power before removing any cover of this equipment.

! Caution – To avoid risk of personal injury NEVER disconnect any pipe, fitting, or filter bowl while the system is pressurized. Always allow pressure to dissipate before opening the system.

! Warning – The Catalytic Process requires very high temperatures. Internal surfaces and copper lines are extremely hot and will cause burns. Always allow the generator to cool before carrying out any servicing.

Introduction

Introduction
The Peak Scientific Instruments range of Zero Air Gas Generators is designed to produce a constant flow of Zero Grade Air with a Hydrocarbon content (as Methane) of less than 0.1 ppm.

Unpacking and Installation Please save the product packaging for storage or future shipment of the generator. Although Peak Scientific take every precaution with safe transit and packaging, it is advisable to fully inspect the unit for any sign of transit damage.

ANY DAMAGE SHOULD BE REPORTED IMMEDIATELY TO THE CARRIER AND PEAK SCIENTIFIC OR THE DISTRIBUTER FROM WHERE THE UNIT WAS PURCHASED. After unpacking and a visual inspection, the unit should be placed in a ventilated area away from direct sunlight. Care should be taken not to obstruct the ventilation holes on the bottom of the unit nor the fan outlet at the Rear. The generator should be placed on a steady and level base. The generator is designed to be installed inside a standard 19” telecom cabinet. The generator requires 4U space overall. Performance of the generator (like all sophisticated equipment) is affected by ambient temperatures and humidity. Prolonged operation in temperatures exceeding 28°C will shorten the life of the unit. Operation in relative humidity exceeding 70% may result in moisture carry-over. Additional moisture traps should be installed downstream of the generator should ambient regularly exceed 70% Rh. and also if the generator is any distance from the application. Moisture traps or coalescers should be located as close to the application as possible. Note should also be taken of the proximity of Air Conditioning outlets. These can sometimes give rise to “pockets” of air with high relative humidity. Operation of the generator within such a pocket could adversely affect its performance.

CONNECTION

Air Connection The Zero Air Generator should be connected to a clean, dry, OIL - FREE source of compressed air. A minimum pressure of 85 psig (5.86 barg ). The inlet and outlet connections are 1/4" BSP female. The Inlet air should conform to the following specifications: Minimum Pressure Maximum Pressure Maximum Hydrocarbon Content 85 psig 125 psig 100 ppm

The inlet air should be oil free and pre-filtered to remove bulk moisture. Although not essential, an air drier up-stream of the generator will ensure a long and trouble free life. Note the platinum catalyst within the Zero Air Catalytic Chamber will become poisoned if it comes into contact with any halogenated hydrocarbons, silicone sprays, silicone greases, phosphorous compounds, lead components, high sulphur vapours or other catalyst poisons. The air supply should be connected to the generator inlet on the back panel left side of the cabinet (looking from the front). The user's application should be connected to the outlet on the right side of the cabinet. To avoid leakage/impurity ingress, use PTFE tape on all fittings. Slowly, turn on the air supply until the required pressure is attained. There is no physical method of restricting the gas output from the generator. The user should therefore ensure that the application only receives a maximum flow not exceeding the rating for the generator. Demand in excess of the rated capacity of will result in higher levels of hydrocarbons in the delivered gas. Electrical Connection Important Electrical Notice This unit is classified as SAFETY CLASS 1 equipment. THIS UNIT MUST BE EARTHED. Before connecting the unit to the mains supply, please check the information on the serial plate. The mains supply must be of the stated AC voltage and frequency. EARTH/GROUND (E): Green & Yellow or Green LIVE (L): Brown Black Neutral (N): Blue White Fuse The generator protection fuse is located within the bayonet cap panel mounted fuse holder on the front panel. The fuse is rated at 10Amp. Connect the generator to a single-phase 110 volt supply using the power cord provided.

Principle of Operation

The ZA070-19R Zero Air generator works on the fundamental principle of Catalytic Oxidation as illustrated in the following pneumatic diagram.

Inlet Filter / Regulator

Cooling Coil

Outlet Cat Chamber

ZAxxx Pneumatic Diagram

Zero Air Generation Inlet air is passed into the Generator via a coalescing filter, which removes bulk moisture and particles down to 0.1 micron. The air is then passed to the 'Zero Air' catalytic combustion chamber. This works on the principle of catalytic oxidation where hydrocarbons from the incoming compressed air supply are cracked to carbon dioxide and water. The hydrocarbon level in the form of methane is reduced to

Commissioning This should be undertaken by a technically competent person. Prior to installing the generator into the Rack Cabinet, remove the lid. Check that all the internal components are securely located and have not moved during transit. Refit the lid. Open the air supply and switch the Power supply ON to unit. Set the regulator on the front panel / Regulator to the desired pressure. Check that the cooling fan at the rear of the generator is operating and exhausting air out of the generator. Check the Digital display on the front panel is increasing temperature Maximum 400° this can take c up to 40minutes from initial switch On.

Maintenance Schedule

WARNING: Servicing and/or repair of the Generator should only be undertaken by a
TECHNICALLY COMPETENT PERSON with the Generator in a safely isolated condition.

Routine Maintenance Due to the simplicity of design and the small number of parts the Peak Zero Air Generator will have a long and trouble free life. However as with all scientific and technical equipment it should be regularly inspected by a competent person and the following points noted. Inlet Filter Condensed moisture should be periodically drained from the filter. Check the front panel Digital temperature is cycling between the temperature of 395° and 400° C C.
