Conventional HVAC and AC systems were not designed for the modern office. Seisou SLOW is a thermal comfort solution for offices built specifically around the problems your team experiences every day.
Forced air from fixed vents creates uneven temperature zones across your office — some desks are freezing while others are sweltering. Employees spend more time adjusting the thermostat than doing their work. This is the most common thermal comfort complaint in commercial buildings worldwide.
Seisou SLOW distributes panels across the entire ceiling, absorbing heat uniformly – eliminating hot and cold spots permanently.
Conventional AC strips moisture from the air as a byproduct of cooling, leaving offices with uncomfortably dry air. This causes dry skin, irritated eyes, sore throats, and increased vulnerability to airborne particles. It’s one of the most-searched air conditioning problems in offices – and one of the easiest to fix with the right system.
SLOW uses no forced air, preserving natural room humidity and delivering healthier air quality for your entire team.
Cooling accounts for 60–70% of the electricity bill in most Indian commercial buildings. Conventional HVAC and AC systems are inherently inefficient — they cool the entire air volume of a room, most of which isn’t occupied. The need to reduce HVAC energy consumption is one of the top priorities for facility managers and property owners across India.
SLOW cuts cooling energy by ~30% by targeting heat at the source rather than battling the entire room’s air volume.
HVAC fans and AC compressors are a constant background noise in most offices. In open-plan workspaces and co-working environments, this noise significantly affects concentration, communication, and productivity. A silent cooling solution for offices isn’t a luxury — it’s a genuine productivity advantage.
SLOW has no fans and no compressor noise. It operates in near-complete silence — invisible to your team.
Traditional HVAC systems require regular servicing, filter replacements, duct cleaning, and refrigerant checks. Any one of these can cause costly downtime and disruption to your operations. For commercial property managers, the need to reduce HVAC maintenance costs is a constant operational challenge.
SLOW has no filters, no ducts, and minimal moving parts — dramatically reducing maintenance requirements and system downtime.
Many Indian commercial buildings — especially older ones — have low false ceilings, insufficient structural clearance, or no existing ductwork. Retrofitting conventional AC in these spaces is expensive, disruptive, and sometimes simply not feasible. Finding cooling options for space-constrained commercial buildings is a real and growing challenge.
SLOW’s slim ceiling panels are designed for low-clearance retrofits — fitting into spaces where traditional systems cannot.
Every specification of SLOW is designed to deliver workplace thermal comfort while minimising energy use, installation complexity, and operational cost.
With no air filters, no ducts to clean, and no refrigerant to manage, SLOW dramatically reduces the ongoing maintenance burden compared to conventional HVAC. Fewer service visits, fewer breakdowns, and a longer operational lifespan mean lower total cost of ownership for commercial property managers and building owners.
No filters, no ducts, no refrigerant.
SLOW is engineered to comply with internationally recognised thermal comfort and green building standards — making it the right choice for organisations with sustainability mandates, green building certifications, and ESG reporting requirements.
Most cooling systems fight heat with cold air — blasting it around your office and hoping for the best. SLOW takes a different approach: it removes heat quietly and directly, without forcing air across your space. The result is a better alternative to traditional HVAC — more comfortable, quieter, and significantly more efficient.
SLOW is engineered for the constraints of real Indian commercial buildings — low ceilings, retrofit limitations, tight construction schedules, and demanding occupants.
ASHRAE thermal comfort standards define the conditions required for occupants to feel genuinely comfortable in a building. SLOW is designed to meet these benchmarks consistently. For organisations with green building targets or ESG commitments, SLOW makes compliance straightforward.

SLOW panels disappear into your ceiling. No bulky units, no exposed pipework, no visual clutter — just clean surfaces that work silently above your team. Thermal comfort technology should be invisible, and SLOW is exactly that. Retrofit-friendly — fits most existing ceilings.

Traditional AC creates temperature gradients that make hot and cold spots in the office unavoidable. SLOW panels distribute heat absorption across the entire ceiling, ensuring temperature uniformity of ±0.5°C throughout the space. Every employee, regardless of where they sit, experiences the same level of comfort. ±0.5°C temperature uniformity across zones

Because SLOW doesn't move air, it doesn't strip moisture from your office environment. The room's natural humidity is preserved, eliminating the dry air, itchy eyes, and respiratory irritation that conventional air conditioning causes in offices. Your team breathes cleaner, more natural air — all day, every day. Natural humidity preserved — no dry air

SLOW is designed from the ground up for retrofits. It requires no ductwork, no major structural work, and minimal disruption to your operations. A typical office zone can be installed in under three hours — making it the most practical cooling option for space-constrained commercial buildings and offices undergoing renovation. No ductwork required — installs in hours
Seisou is currently running pilot programmes with select offices and commercial spaces across India. If you’re ready to explore a sustainable, energy-efficient alternative that genuinely works – Lets Talk!
