LT Smart is building a sustainable business that grows over time. The group unites companies and products that solve real problems in buildings, energy and infrastructure, and make everyday living simpler.
“A Smarter Way of Living” is the principle behind every company in the group. Each one is a specialist in its own field, and together they cover the full life of a modern building: the glass in its walls, the energy on its roof, the wiring behind it, the power that keeps it running and the sensors that keep it safe.

Power continuity for data centres that cannot go dark.
LT Smart Power designs and delivers turnkey power for data centres: Power Protection backed by diesel and gas generator sets, automatic transfer switching and paralleling, with support for the life of the site.
Data processing equipment is the brain of the business, so every system is engineered for the site, from a single data hall to a multi-megawatt campus.

The data centre power chain
Mains and ATS
Automatic transfer switch cabinets watch the grid and hand over the moment it fails.
Dynamic UPS
A kinetic energy module carries IT and cooling loads with 0 ms transfer and no batteries.
Generators
Diesel or gas sets start and take the load, with black-start and seamless reconnection to the grid.
Paralleling
Sets run in parallel for redundancy, and more can be added as the site grows.
Turnkey systems
Custom builds around the generators and dynamic UPS, so a data centre gets one engineered power system from one supplier, from design and installation to testing and support.
- Automatic transfer switch cabinets
- Paralleling and synchronisation panels
- Exhaust aftertreatment
- Hybrid and energy storage integration
- Genuine spare parts and 24/7 support
Standby diesel generators
Cummins-engined gensets from 24 to 4,125 kVA standby, in silent and containerised builds, to keep data halls and cooling running through any outage.
Gas generators
MWM natural gas gensets up to 4,500 kW for prime and continuous power, combined heat and power, and sites with limited grid capacity.
Dynamic UPS: the Hitec PowerPRO range
A kinetic energy module, generator and diesel engine in one unit. No batteries, no lithium or cobalt, and it carries cooling loads as well as IT.

PRIVIGLAZE is the smart glass company of LT Smart. It designs, laminates and installs switchable glass that turns from clear to frosted in a fraction of a second, so rooms keep their light and openness without blinds, curtains or solid walls.

How switchable glass works
PRIVIGLAZE uses PDLC (polymer dispersed liquid crystal) film. The film is laminated between two panes of toughened glass, or applied to existing glass as a retrofit film.
Power off
Liquid crystals sit at random and scatter light. The glass is frosted and private, but daylight still passes through.
Power on
A low-voltage current lines the crystals up and the glass turns clear in about 0.01 seconds.
Control
Wall switch, remote, smartphone app or voice, or integration with Crestron, Lutron and Control4 building systems.

Products and solutions
Switchable smart glass
Laminated, toughened PDLC glass for partitions, doors, windows and bespoke glazing. Made to measure in the UK.
Retrofit smart film
Self-adhesive switchable film that adds privacy to existing glass without replacing it. Ideal for refurbishments.
Office partitions
Meeting rooms, boardrooms and pods in frameless, curved, timber-framed and double-glazed builds.
Smart blinds
Glass split into zones that switch independently, so part of a pane can be frosted while the rest stays clear.
Roof lights
Switchable skylights and lanterns that control glare and privacy while letting daylight through.
Rear projection
In frosted mode any PRIVIGLAZE surface works as an HD projection screen, at no extra cost.
Frameless bifold doors

SmartLinkX (IoT devices and platform), LT Smart Power (dynamic UPS and generators for data centres), RENUiTT (solar, battery storage, EV charging and heat pumps), PRIVIGLAZE (switchable smart glass) and LTS Electrical (electrical supply and installation).
How does a dynamic UPS keep a data centre running?
A dynamic UPS combines a kinetic energy module, a generator and a diesel engine in one unit. When the mains fails it carries the IT and cooling load with 0 ms transfer time and no batteries. LT Smart Power supplies Hitec PowerPRO units from 470 to 3,600 kVA each, combined into systems of up to 100 MW.
How does switchable smart glass work?
PRIVIGLAZE glass contains PDLC (polymer dispersed liquid crystal) film. With the power off it is frosted and private; with a low-voltage current it turns clear in about 0.01 seconds, letting through 91% of visible light and blocking 99% of UV.
Does RENUiTT install solar panels and EV chargers?
Yes. RENUiTT designs and installs MCS certified solar PV, battery storage, EV chargers from 7.4 kW home units to 320 kW rapid chargers, and air source heat pumps for homes and businesses across the UK. Every solar system includes a 10-year maintenance plan.
