HIGH SECURITY VENTILATION LOUVRES
Applications These heavy duty steel Louvres are ideal for a wide range of applications including server rooms, generator housings, air conditioning systems, sub stations and so on. They can be made to almost any size to suit a wide range of ventilation requirements.
Anti-Ligature Features The unique Surelock McGill Anti-Ligature Louvre Range is used in areas such as seclusion rooms, secure hospitals, generator housings and prisons.
Finishes
Surelock McGill have been manufacturing and installing high performance door locking and bolting systems, as well as ancillary products, for over 50 years. Intensive research and development, together with the embracing of new technologies and materials as they evolve, means that our products provide the most robust and sophisticated security available.
Our products are tested for their resistance to many forms of threat (for example, security, re, blast, ballistic attack). They are also designed, tested and certi ed for the health and safety duty of care that is required today.
The development of new products has been integrated with our regime of testing and approvals to maintain the supply of products with certi cation to important UK and European standards throughout the process.
Hostile Environments Surelock McGill products are widely used on offshore oil platforms and generally in the petro-chemical industry. This is due, in part, to their resistance to the privations of such environments. The same considerations and their inherent resilience also lead to their use in securing remote stations used by police response units and the armed forces.
Total Commitment, Comprehensive Service Surelock McGill offers a comprehensive service to ensure integrity and security:
Operational analysis and technical advice Site survey and scheduling Product manufacture and supply Bespoke design systems Installation
Planned maintenance On-going support Standard packages
Customer Care Surelock McGill customer care is second to none. That is why we can boast an exceptional level of customer loyalty. Solid business relationships have been built on the trust earned by our dedication to providing the best security solution for every challenge that our customers confront us with.
Quality Statement Our continued commitment to product excellence and accreditation to ISO 9001: 2008 throughout the group ensures unequalled customer satisfaction and is our ‘Seal of Excellence’.
Applicable Standards and Accreditations:
ASSESSED TO ISO 9001: 2008 CERTIFICATE NO. 516

Using Bernoulli’s equation, it can be shown that for a parallel duct system that exhausts into, or takes air from the atmosphere, ∆p/q = 1 + ∆P/q.Total non-dimensional static pressure drop for 0.2m/s flow rate,∆p/q = 1 + ∆P/q = 1 + 6.71 + 3.02 = 10.73Louvre | Slotted plateHence the static pressure drop ∆p = 10.73 x (½ x 1.2 x 0.2²) = 0.26 Pa.
Pressure drop across Louvre as a function of approaching flow velocity (high flow velocities).
