1. Why This Decision Matters (Dairy = High Frequency + High Sensitivity)

Dairy and grab-and-go categories (milk, yogurt, sandwiches, ready meals) are high-velocity SKUs with:

• Frequent customer touchpoints (daily consumption)
• Strong impulse triggers (visibility + accessibility)
• Strict temperature requirements (2–8°C typical)

This creates a core operational trade-off:

Sales efficiency (open multideck) vs energy efficiency (glass door)

---

2. Open Multideck Chillers: Where They Win

2.1 Frictionless “Grab & Go” Behavior

Open multideck (air curtain merchandisers) eliminate the “door barrier”, reducing:

• Decision friction
• Physical effort
• Time-to-purchase

Result: Higher conversion rate per shopper

Best for:

• Yogurt cups
• Fresh milk (daily purchase)
• Ready meals / salads
• Drinks in high-traffic zones

---

2.2 Stronger Visual Merchandising

Open cases provide:

• Full product exposure (no reflection, no frame blocking)
• Better planogram visibility
• Easier category segmentation (brand blocks, price tiers)

Result: Higher basket size via impulse add-ons

---

2.3 Faster Restocking & Operations

• Staff can replenish without opening doors
• Reduced congestion during peak hours
• Better for high turnover SKUs

Especially critical in supermarkets with >500 daily dairy transactions

---

3. Glass Door Merchandisers: Where They Still Win

Despite sales advantages, doors dominate in:

3.1 Energy Efficiency

• Up to 30–60% lower energy consumption
• Stable internal temperature
• Less compressor cycling

Critical for:

• Large-format supermarkets
• High electricity cost regions (EU, some US states)

---

3.2 Temperature Stability & Compliance

• Better for sensitive dairy (cream, fresh milk, probiotics)
• Reduced risk of temperature fluctuation

---

3.3 Shrinkage & Loss Control

• Limits casual handling
• Reduces product exposure

---

4. Decision Matrix: Dairy & Grab-and-Go

Scenario	Recommended Solution	Why
High traffic / convenience store	Open multideck	Maximize speed + impulse
Premium supermarket dairy zone	Hybrid (open + doors)	Balance sales + energy
Low traffic / bulk retail	Glass door	Reduce operating cost
Ready-to-eat / lunch rush zone	Open multideck	Fast access = higher turnover
Night operation focus	Glass door or open + night curtain	Energy control

---

5. The Hybrid Strategy

Top-performing supermarkets rarely choose “only one.”

Recommended layout:

• Front zone (high traffic): Open multideck
• Back/side zone: Glass door merchandisers

Logic:

• Capture impulse at entry
• Preserve energy in lower-traffic areas

---

6. Night Curtain: The Key to Fixing Open Case Energy Loss

If you use open multidecks, night curtains are non-negotiable.

What is a Night Curtain?

A retractable cover used after store hours to:

• Reduce cold air loss
• Maintain internal temperature
• Lower compressor workload

---

Real Impact:

• Energy savings: 15–35%
• Faster morning temperature recovery
• Extended equipment lifespan

---

Best Practice:

• Train staff to close curtains immediately after closing
• Combine with LED + fan speed control
• Use for all non-24h stores

---

7. Layout Playbook for Dairy & Grab-and-Go

7.1 Zoning Logic

• Eye-level = high-margin items
• Middle shelves = core dairy (milk, yogurt)
• Bottom = bulk packs

---

7.2 SKU Strategy

• Limit SKU overload → keep fast-moving SKUs front-facing
• Use vertical blocking for brands

---

7.3 Temperature Zoning

• Top shelves: slightly warmer (ready meals)
• Lower shelves: colder (milk, fresh dairy)

---

8. Final Recommendation

If your store focuses on dairy + grab-and-go turnover, the optimal strategy is:

Use open multideck chillers in high-traffic zones
Add night curtains to control energy loss
Combine with glass door units for low-traffic areas

---

9. Quick Takeaway

• Open multideck = sales driver
• Glass door = cost controller
• Night curtain = bridge between both

10. FAQ

Q1: Are open multideck chillers safe for dairy?
Yes, if properly maintained and within 2–8°C, they meet supermarket standards.

Q2: Do open cases increase electricity cost significantly?
Yes, but this can be reduced with night curtains and smart layout.

Q3: Which is better for grab-and-go food?
Open multidecks—because speed directly increases conversion.
