The Infinity XE 50 Series delivers performance and value beyond expectations,
oering a pure and reliable source of gas. These perpetual flow nitrogen generators
are suitable for a variety of applications in your laboratory.
These models provide a source of nitrogen gas with other features including:
• Single Source Solution - One generator can cater for the requirement of multiple
applications & multiple laboratories on site
• Durable - Few moving parts with minimum maintenance requirements
• Quiet in operation – Silent whilst operating
• Mobile – Flexibility to position the generator where required
• Simple installation – Generator designed as a plug and play system
• Economical – More cost eective than any other gas supply method
• Convenient – Gas on demand, no hazards, no need to worry about running out of
gas
• Eco-mode – Energy ecient eco-mode ensures low running costs
The Infinity XE 50 Series generators are based on proven technology, and selectively
remove oxygen, moisture and other gases to leave clean, dry, phthalate free nitrogen.
To ensure these Generator models meet our high expectations with regards to
reliability and performance, we have tested them extensively at our manufacturing
plant and with end users around the world to ensure reliability and longevity of the
system.

Unpacking
Although Peak Scientific takes every precaution with safe transit and packaging, it is
advisable to fully inspect the unit for any sign of transit damage.
Check ‘SHOCKWATCH’ and ‘TIP-N-TELL’ labels for signs of rough handling prior to
unpacking
Any damage should be reported immediately to the carrier and Peak Scientific or the
Peak Partner from where the unit was purchased.
Follow the unpacking instructions posted on the side of the crate. It will require two
people to remove the unit from the shipping crate and to manoeuvre the generator to
the desired location.
Please save the product packaging for storage or future shipment of the generator.
Note: Included with the generator is a “Fittings Kit” containing mains power leads
for UK, EU & US and also all the required fittings and warranty registration card. Be
careful not to discard these with the packaging.

Installation
Generator Environment
The generator is designed for indoor use only. It should be installed adjacent to
the application(s) it is supplying. If this is not convenient then the unit can be sited
elsewhere, however, consideration should be made of the lengths of pipe runs as
pressure drops can result from extended runs of pipe.
Performance of the generator is aected by ambient conditions. Note should also be
taken to the proximity of Air Conditioning outlets. These can sometimes give rise to
“pockets” of air with high relative humidity. Operation of the unit within such a pocket
could adversely aect its performance. Consideration should also be given to the
air flow around the unit. It is recommended that an air gap of 75mm (3”) should be
maintained down both sides and at the rear of the unit. Please refer to the drawing
below for the general dimensions of the unit.
The generator should be situated in a well ventilated environment, with at least a
75mm (3”) air gap all around it and should be positioned such that it can be easily
disconnected from the mains supply if required
Minimum Operating Ambient Temperature: 5 °C (41 °F)
Maximum Operating Ambient Temperature: 30 °C (86 °F)

Generator Overview
General Dimensions
The generator must always be placed on a flat, level surface. Failure to
do so will aect the performance of the generator.

Inlet Air Quality
The Nitrogen Generator should be connected to a ISO 8573-1:2010 (1:4:1) source of
compressed air. A minimum pressure of 60 psig is required for ecient operation of
the Generator. Any doubts as to the suitability of your compressed air supply should
be referred to the factory for advice.
A MAXIMUM OIL VAPOUR CONTENT OF 0.01 mg per m^3 is PERMISSIBLE

Electrical Connection
Connect the generator to an appropriate 85-264 volt single-phase supply, refer to
the generator serial plate for input specification and ensure your supply matches the
requirements.
If the appropriate power cord is not supplied; a new plug, rated to at least 12 amps,
can be fitted by a qualified electrician.
If an appropriate mains power cords is not supplied or a substitute one is used then
ensure that all components of it the plug, cord and connector have adequate ratings
for the generator and appropriate approvals for the country of use. Failure to do so
could cause damage to the generator or risk overloading of the power cord
This unit is classified as SAFETY CLASS 1. 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.

Electrical Panel Access
Changing settings within this enclosure may adversely aect the
operation of the generator. This enclosure should not be accessed
unless by or under direct instruction from a trained individual.
WARNING

Normal Operation
The Infinity XE 50 Series Gas Generators are designed specifically to minimize
operator involvement. Given that the systems are installed as described in
earlier sections and is serviced in accordance with the specified maintenance
recommendations (see Service Requirements), then it should simply be a matter of
turning the Generator on when it is required.
The Generator will automatically produce the factory set flow and pressure as detailed
in the Technical Specifications.
On Demand Gas
The generator will produce nitrogen on demand. If the application is operating
and requires a gas flow, the system it is connected to will supply this to suit the
requirements of the application. If the application requirement for gas stops, the
system will also stop. If the demand from the application starts again, the system will
detect the demand for gas and will automatically start again to suit the demand.
Eco Mode
When demand from the instrument is below 1.2L/min the Infinity XE generator will
stop demanding air from the external compressor. If demand from the application
starts again, the system will detect the demand for gas and will automatically start up
again.

Page 20
Commissioning
With the generator installed as previously described, connect the application to the
Nitrogen output port and open the air supply to the unit. On reaching operational
pressure the generator will produce Nitrogen at the customer-specified purity. The
design of the generator is such that it will deliver up to the rated output flow of
Nitrogen, determined by demand of the consuming equipment. Rated flow, purity
and pressure are customer-specific and dependent on inlet conditions being met as
detailed on the individual generator
The design of the generator is that it will deliver variable purity dependant on the
inlet pressure and outlet flow rate. Outlet pressure may be adjusted by the pressure
regulator on the rear of the unit, allowing for up to 20 psi pressure drop across the
system. Should the demand for the nitrogen stop, the generator will automatically go
into "eco-mode" (refer to page 18), shutting o the air inlet. Once the demand restarts
the generator automaticcaly resumes producing Nitrogen. The generator is protected
from over pressurising.
Tubing Lengths
The diameter of the tubing which will be connected to the gas outlet
is important and is determined by the length of tubing required.
Failure to follow these recommendations could lead to pressure
between generator and application.
> 10 - 40 meters: Use 12/10 (12mm O/D, 10mm I/D) Tubing.
> 40 metres: Please contact Peak Scientific with the relevant distance
andwe will calculate the flow resistance and the
tubing size required.
The imperial equivalents are: 12/10 = 1/2” O/D, 3/8” I/D.
Air input tubing for 5030 & 5040 is not supplied. 16mm OD, 12mm ID PTFE Tubing is
reccomended.
CAUTION
