Research & Development

Precision in Every Detail

Every SUNNAI appliance reflects months of development, guided by German engineering standards and deep collaboration with chefs, designers, and brand partners. Our R&D team continuously refines:

Temperature and airflow logic for multi-zone precision

Noise and vibration control for quiet, stable operation

Shelf geometry and interior layouts for optimal capacity

Material selection, industrial design, and usability

We Don’t Just Manufacture Coolers. We Architect Climate Logic.

From Tier-1 Components to Total System Optimization

World-Class Compressor

Vibration-Free Stability

German-Guided Insulation Technology

Our strategic partnership with LG, Embraco, and Jiaxipera ensures every unit delivers superior refrigeration efficiency, rapid pull-down times, and ultra-low noise decibels (<40dB)

Specifically engineered for wine and cigar storage, our damping systems neutralize micro-vibrations that could disturb chemical aging processes.

Utilizing high-density, German-made insulation materials to minimize heat transfer and prevent external condensation, even in high-humidity environments.

Micron-Level Adjustment Precision

Our advanced algorithms dictate the perfect storage climate

0.1°C Ultra-Refined
Adjustment

For medical and laboratory applications, our DC fan driven systems allow for 0.1°C increments to maintain a constant 2°C to 8°C range.

Active Humidity
Equilibrium

Our patented technology intelligently maintains humidity around 75% RH for dry-aging and within the 65–75% RH range for cigars

Dual-Zone
Flexibility

Our unique motor design allows dual-zone wine coolers to function as a single large zone when needed, optimizing energy consumption and storage versatility.

Materials dictate longevity and enduring performance

Customized Internal Liners for Specialized Media

Food-Grade 304 Stainless Steel

Cedar Wood Shelving

High-Retention Textured Liners

Used in our beverage and dry aged lines for its superior thermal conductivity, ease of sterilization, and corrosion resistance compared to standard plastic.

Crafted to regulate moisture without warping, our cedar shelves resist bowing while providing a natural defense against tobacco beetles.

Our textured wall design in wine coolers optimizes internal airflow and humidity retention while allowing for multi-level adjustable shelving.
