Holdstrōm · The Sōren difference

Sōren control detail

Built around one promise: a feeling of permanence.

Many cabinets cool by convection. Sōren does not, and the difference decides how the leaf matures. Together they are the difference between a cabinet that stores cigars and one that ages them.

CONVECTION SŌREN · COMPRESSOR

Compressor, not convection

Thermoelectric convection cabinets can only pull a few degrees below the room and struggle to hold humidity. Sōren runs true compressor refrigeration, holding your set point through summer heat.

ROOM · JAN–DEC SŌREN · 18ºC HELD

Holds the climate, even in winter

Cooling-only cabinets drift the moment the room turns cold. PTC heating lets Sōren hold your set point through winter, season after season.

TEMPERATURE CHANNEL HUMIDITY CHANNEL

Temperature and humidity, kept apart

Each travels its own dedicated air channel. Cooling never dries the cabinet and humidifying never warms it. 360° surround airflow carries that climate around the whole interior, with no wet pockets and no dry corners.


Stability

Set it once. It never wavers.

Adjustable set point · 16–22 °C · 60–80 % RH

Sōren corrects drift before it becomes change, so the cabinet never jumps between extremes. No heat shock, no humidity shock. Your cigars rest undisturbed, season after season.

TEMPERATURE HUMIDITY

Independent temperature and humidity channels

Cooling and humidification run on separate channels. Adjust one and the other holds.

CYCLING SŌREN · MODULATED

Variable speed compressor

An inverter compressor modulates its output instead of cycling hard on and off. No temperature spikes, lower noise, lower power draw.

THERMOSTAT SŌREN · PID

PID smart climate control

An on/off thermostat overshoots, then undershoots. The Sōren PID controller learns from historical fluctuations and corrects before a change becomes meaningful.

Uniformity

Every cigar, the same climate.

A cabinet can hold a perfect average and still age every shelf differently. Sōren circulates air and humidity so the lowest cigar lives in the same climate as the highest.

360° SURROUND

360° surround air circulation

Air and humidity are distributed in three dimensions around the interior instead of falling from a single vent. No wet pockets, no dry corners, no frost.

RISING HUMIDITY PTC FLOOR

PTC floor heating

A self-regulating ceramic element warms the cabinet floor the way underfloor heating warms a room. Rising warmth carries moisture upward instead of letting it pool at the base.

U · SMOOTH WALL S-FOLD · ×20 SURFACE

S-shaped vapour membrane

Humidity leaves an S-shaped membrane as vapour, never as mist, and never wetting the leaf. The folded surface gives up to twenty times standard humidifying output.


Purity

Nothing reaches the flavour.

Sōren interior detail

Ageing rewards patience and punishes intrusion. Ammonia, light, and condensation are each turned away before they can dull what the years are building.

AMMONIA NO PURIFICATION SŌREN · WATER-ION

Water-ion air purification

Cigars release harmful ammonia as they age. A nanoscale water-ion generator decomposes ammonia into harmless water vapour.

SPANISH CEDAR

Spanish Cedar interior

Shelves are full Spanish Cedar, the wood the ritual has always asked for. It deepens flavour, buffers moisture while staying breathable, and resists insects, rot and mould.

Full Cedar lining, an option on Sōren Lux
UV · UVB LOW-E GLASS

Low-E glass door

Low-emissivity glass blocks light transmission and resists condensation, so neither sun nor damp ever touches the leaf.

Living with it

You'll forget it's running.

At rest ≈ 35 dB

A cabinet should serve the ritual, never become one. Sōren runs at the hush of a bedroom at night, waits months between refills, and answers from wherever you are.

60 dB · SPEECH SŌREN ≈ 35 dB

Ultra-quiet compressor

A back-pressure compressor, matched to the gentle cooling a humidor needs, runs quiet with low vibration. A loud conversation is 60 dB.

MBP on Sōren and Pro, HBP on Lux
FULL MONTHS BETWEEN REFILLS

Recirculating water reservoir

A bottom-mounted recirculating tank holds weeks to months of humidity between refills. It lifts out for cleaning so nothing settles in the water.

TEMPERATURE HUMIDITY · LIVE

Touch panel, lock and Wi-Fi

A black LCD panel adjusts climate without opening the door. A fingerprint lock secures itself on close, and the app draws temperature and humidity as a live curve, from anywhere.
